It's now 2020-11-05 and I believe the problem is fixed! yay!
I have not seen the issue occur for some time.
Close it; but let us try REALLY hard not to let a regression slip in some day
in the future.

Thanks for getting it fixed.

Thank you for your response. Meanwhile I whip out my Kubuntu 16.04 distribution
with stable Plasma and replace it with latest KDE Neon and the bug doesn't
reproduce there. I also install Nvidia proprietary driver. So, the hardware
configuration and driver is similar.

I would like to also add that the driver version on each distribution might be
different. I also use the same Xorg.conf file.

However, I can not confirm that the problem is fixed, because in the past week
I didn't use konsole much often. But, when I use it it didn't cause any CPU
heavy usage.

Did you test this issue on Kubuntu 16.04 or you try only on specific
distribution?

I am glad I receive feedback from KDE.

I use stable KDE plasma 5.8.8 on my Kubuntu 16.04 and the issue is still
reproducible. Today Konsole took full power of one of my core. I use NVIDIA
384.90 proprietary driver.

Does any of the developer know about this issue? It seems that nobody care of
quite important bug. But, this is one of these bug that destroys your whole
experience with the environment. Because, as a developer I use terminal
constantly. I hope somebody will fix it soon.

--- Comment #93 from Sergio  ---
Unfortunately running things under strace just to get rid of some timing race
is a bit expensive in terms of wasted resources. 

>From the strace manual:
A traced process runs slowly.

This is because strace operates in a slightly violent manner: pausing the
target process for each syscall so that the debugger can read state. This
happens twice: when the syscall begins, and when it ends.

Incidentally, this is possibly the reason why strace is effective in working
around the bug as it changes timings in rather strong way. 

So, it may be better to rely on nouveau (if possible) or on some other terminal
emulator like the one from LxQt (if it is not possible to use the nouveau
drivers) for the time being. Fortunately, the KDE Konsole seems to be the
single application affected by this (timing?) issue, which makes a replacement
possible (even if obviously undesirable).

This had been gone for me for a long time with Plasma 5.8 on Linux Mint 18,
with the Nvidia 384.90 driver.  However, at some point, the issue has returned.
 This issue is therefore not just a 340 driver problem.  The only reason I
noticed it was because I have a CPU temperature desktop widget loaded, and
noticed it was a bit high.  Lo and behold, a rogue Konsole process was running
and driving one of my CPU cores at 100%.

Thanks to antonio for the strace workaround.  I'll give that a go!

Same problem :
Opensuse Leap 42.1 
Kernel 4.9.0-4
Nvidia 340.101 patched for 4.9 kernel series + KDE 
KDE Frameworks 5.29.0
Qt 5.7.1

I found this workaroud : if konsole is executed under strace the problem
doesn't occur. So, in KDE Menu Editor you can change "konsole" command into
"strace konsole".

A reflection, offtopic.

After a few years kubuntu 14.04 was relatively stable, now it is without
support and we have to use 16.04 very unstable, within 3 years, when it is
stable we will again have to undergo another unstable version.

Have we gone crazy?

I've tried:

Without any composite.
Without any window manager.

And the error is always produced.

As I see that no one is trying to solve this and other problems of stability
with Plasma, I happened to Trinity and problem solved for me.

This is very strange. I experienced this problem on Kubuntu 15.10 but then
after upgrading to 16.04 it disappeared, but now after upgrading to 16.10 it
came back! I would have to agree that this is some kind of race condition only
getting triggered by a combination of different driver and library versions
etc. This particular system is using the Nvidia legacy driver 340.98

I absolutely have this issue, too, using Kubuntu 16.10 Yakkety Yak and
nvidia-340.98.

After I tried to reproduce my (supposedly unrelated) konsole crash issue I
closed every konsole window. There was no 100% process running then, I checked
that. Way later I noticed one cpu core was running at 100% and it turned out it
was a konsole process.

So, we have users who saw this bug with xenial and then the bug go away with
yakkety, but there are also users (at least me) who did not see the bug with
xenial and see it with yakkety. Then we have users on nvidia 361 before 18 see
it, then see it disappear with .18 and reappear again with .28 (when possibly
nvidia had never touched anything directly related to the issue in the driver).

This looks very much like an issue triggered by timings of events / races.

And it is very much possible that noveau cures it not because it has "better
opengl" but because it is slower in some paths, significantly changing the
timing of things.

Can it be a Qt issue.

Might this be a different bug? The problem here isn't actually konsole
crashing, rather than konsole process running in the background consuming 100%
of a cpu core, after being "exited" by the X button.

For the past weeks I messed around with this one and found out that if I open
two different konsole instances, I could close them both without the cpu
drainage. This might explain the complicated threading issue?

Anyway, after upgrading to Yakkety (Ubuntu 16.10), I found that the bug has
disappeared/fixed/gone_in_a_place_where_good_bugs_do_bad_things . Running with
the good ol' nvidia 340.98.

Note that a comment in the bug thread on the nvidia bug tracker states: "From
what I've seen it may not be the nVidia driver which is at fault. There seems
to be a complicated threading issue which might or might not be caused by the
driver...it may just be this driver exposes the issue differently."

The fact that some people saw the issue even in Xenial with Nvidia 340 and I
did not, as well as the fact that some report that on more modern graphics
cards the issue disappeared with nvidia 361.18 and reappeared in 361.28 seems
to confirm that this may just be a race somewhere (Qt?) and not a bug in the
nvidia drivers.

Is there a Qt bug open on this?

 CC||sergio.calleg...@gmail.com

--- Comment #79 from Sergio  ---
I have started to see the issue on a Kubuntu Yakkety (16.10) machine that uses
Nvidia Quadro FX 570 graphics. The graphics card is supported by the Nvidia 340
legacy driver. The software included in Yakkety is plasma 5.7.5, framework
5.26.0, konsole 16.04.3, QT 5.6.1.

The symptoms seem to be exactly those described here. Closing the konsole a
process is left behind, in my case using 100% cpu. Furthermore, there are
occasional crashes of the konsole on exit due to issues with corrupted double
linked lists.

Moving to the noveau driver resolves both the issues (but brings in other
problems on its own).

The interesting part is that the same machine with exactly the same hardware,
was not showing this issue with ubuntu Xenial, while others report the issue
also on Xenial.

I thus wonder if the bug may be triggered by some sort of race or
ordering/timings in which events occur, that may be influenced by both the
hardware and the software stack. If this is the case, the fixing of the issue
in the most recent Nvidia drivers could be just luck. For sure, the issue is
still present with the latest Nvidia 340 drivers, so please reopen.

Even if this is a bug with the Nvidia legacy opengl implementation, avoiding
triggering the issue in the beginning in the konsole would be the best. This
should be possible as the Qt terminal is reported not to have any issue.

Yes, I can confirm, the bug is still existent. As I cannot change my nvidia
drivers (as I need legacy drivers), they are still installed. So on my system
KDE changed, but not the drivers.

Another hint: Maybe there is a relationship with another bug. I found out, that
SDDM can not be started, when nvidia drivers are used. Just a thought, maybe
there is a relationship somehow...

Another workaround.
The failure (at least in my case) occurs when the last instance of konsole
closes. Then the solution is that there is always an instance of konsole in the
session.

Add to the start of session: /usr/bin/konsole --background-mode

I also use Nvidia 340 drivers.
All these days after I installed the new Mint KDE 18 OS , I used to run the
konsole to make my system better , to take updates , to fix my fstab ,etc etc
and closing this application, I actually had less than the 50% of my CPU
available…
Finally I noticed that konsole was running to the backround. Lucky me !!!
This is the main reason (I guess), I found plasma desktop very heavy and I
wanted to change my desktop !!!
Because of a konsole with psychological problems…….

Same issue here:  close Konsole using window 'X" and one processor goes up to
100%; have to kill it; if I close the last tab with it's 'local X' no problem;
if I close using 'exit' at CL, no problem.

Older HP laptop; GeForce 8600M GS; nVidia patched 340.96 driver.

I understand this is really an nVidia issue but here's MY issue with KDE:  no
other terminal program I use under KDE except Konsole has this problem,
therefore, is this REALLY solely nVidia's issue or are 'you KDE folks' just
kicking the turd down the road?  This has been going on for way too long
(years, for crap's sake), how about you 'KDE folks' own up to it and fix it? 
You're looking like a bunch of goofballs right now...

Unfortunately, my GeForce 9500M GS card on my laptop is too old to even have
any options for GLVND for the latest driver available for it, v. 340.  I'm
stuck with this bug.  Other than this issue with konsole, KDE Plasma 5 was
exceptionally snappy.  It put Windows Vista to shame.  I'm saddened that I seem
to have no workaround for this issue.  The new 364 driver does not support my
card.  I could go back to the nouveau driver, but then I can't play some of my
old video games.

I could stop using konsole and switch to Gnome terminal or something else, but
I like konsole's customization options for theming.  Also, I am worried that I
will eventually run into this issue again with a different KDE application and
not even realize that my CPU is burning up until it's too late.  The only
reason I caught this was that I was monitoring resource usage after a fresh
install of Kubuntu 16.04.

So, no, this issue is not resolved for me.  I'd like to stick with konsole if I
can, and truly have a fix that works for my graphics card and will work for
other applications that could have the same underlying problem.

Please consider reopening this issue.  It would be nice to find a workaround on
the KDE side of things.

This has been a problem on my OpenSUSE Leap 42.1, and I am using the Nvidia
361.48 driver which uses the legacy non-GLVND.
The Nvidia 364.x driver will make GLVND default, so if that will fix the
problem all we have to do is wait until that version of the driver is
released..

Mike: My guess would be that it depends on whether you use the glvnd library or
not. 

Could you try installing the driver with it and see if the problem persists? 
I can't reproduce it when using glvnd  (which, despite the problem it had,
would be my recommendation)

It appears your hypothesis is correct, when I reinstalled the driver with: 

NVIDIA-Linux-x86_64-361.28.run -s --dkms --install-libglvnd --glvnd-glx-client

I am not able to reproduce the bug. I assume GLVND was by default in the beta?

This needs to be re-opened due to the fact that 361.28 has a regression that

Konsole uses 12% of my CPU. When I run multiple instances of Konsole, and close
them using the close button on the window, it remains in the background. I use
QTerminal instead, no issues. I wonder how that could be related to NVidia

Have they fixed all the problems 361.16 was having with KDE and Steam?  I'd
rather click the lower right close button on a terminal than have my system
unstable.

Also, 361.16 is still the latest in the ppa.  It'll be much easier to back out
from a ppa install than manual install.  I'll wait until .18 is in the ppa to
give it try.

[konsole] [Bug 343803] Konsole keeps running in background after closing window with nvidia drivers

[Jonathan Ringstad via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=343803

--- Comment #41 from Jonathan Ringstad  ---
I had a look and found a bit of additional information:

- The hang occurs when the libc exit handler cleans up the shared libraries of
the program, so when the process starts to hang, no actual konsole code is
running anymore. So that seems to make it very unlikely that the fault is with
konsole
- the hang occurs inside _nv014tls in /usr/lib/libnvidia-tls.so.358.16 (nvidias
thread-local storage library used by GL, GLX et al), where the function falls
into an infinite loop. Injecting a debugger and forcing it to return, results
in konsole exiting normally.
- The libc exit handler calls /usr/lib/libGL.so.1's .fini section (I think)
which calls the problematic _nv014tls from the libnvidia-tls.so.
- libGL gets loaded because konsole (well, Qt, I think -- konsole does not
touch GLX directly) wants to do glX* calls such as glXChooseFBConfig,
glXGetFBConfigAttrib, glXGetVisualFromFBConfig. no GLX context is ever
initialized or destroyed from what I can tell, however (which is a bit strange,
but I think should be perfectly legal to do. All the functions that are called
do not require a GLX context to be present, from what I can tell.)
- Re-running the exact same sequence of GLX functions in a different process
does not lead to such a hang. Traceback: http://dpaste.com/0RWSDK7 I re-ran the
traceback a few thousand times without a hang. So there's probably at least one
more ingredient necessary to make the hang happen.

That's about as far as I got. As a workaround it might be possible to make Qt
not interact with GLX (if that's possible), since it's not used anyway. It
seems pretty likely to me at this point that the bug is in the nvidia client
driver, but I suppose there is still a chance the bug is in Qt. I think the bug
is definitely not in konsole.

I didn't manage to produce a minimal test-case, unfortunately. To get there, it
might be useful to check if konsole loads any other nvidia client drivers, and
if yes, how it interacts with them.

Though actually, QT_XCB_FORCE_SOFTWARE_OPENGL is probably also ineffective
because the proprietary driver replaces the system libGL with its own version
that probably does not support LIBGL_ALWAYS_SOFTWARE. So if it doesn't help,
that'd be why.

That does indeed not fix the issue, as the issue is not with OpenGL but with
GLX. The GLX calls are made all the same. 

You can force software rendering through mesas llvm-pipe by adjusting your
library path to include the mesa libGL.so first (mesas llvm-pipe driver can
pretty much co-exist with any other driver without big issues -- useful for
testing), but that is a rather drastic measure and not a solution I would
recommend for end-users as workaround for several reasons.

As you can see, the problem has been reported to Nvidia without success for
now. Maybe if you and the other comment there we can make things move. Plasma 5
can't stay with this problem.

I believe I observed the breakpoint being triggered many times, but I'm not
sure how thoroughly I actually investigated that. I can collect more data later
today to (hopefully) answer the question definitely.

If it does indeed just hang in the  nvidia function without ever returning to
konsoles code, then I would agree that that makes it a much more likely
candidate for being a bug in the driver; but that's still not entirely a sure
thing.

I can try to make a debug-build of konsole to isolate the driver<->konsole

We really don't know anything about where the issue is. All we know is that a
function from the nvidia driver is getting called repeatedly, and that's where
CPU time is going. I can easily invent a dozen scenarios that would cause this
type of behaviour, yet it would still be my fault (the simplest being to just
call whatever driver function in an infinite loop.)

Seeing how the nvidia driver is generally very solidly engineered (the most
reliable of all drivers by a HUGE margin, in my experience) I see no particular
reason to assume it's the drivers fault.

[konsole] [Bug 343803] Konsole keeps running in background after closing window with nvidia drivers

Here it happens only sometimes.
But 2 things:

starting Konsole from a xterm:

QCoreApplication::arguments: Please instantiate the QApplication object first
QDBusConnection: session D-Bus connection created before QCoreApplication.
Application may misbehave.

I'm trying with strace but obviosly, does not happens with strace but the last
line is:
+++ exited with 0 +++

Why "exited with 0 " ? Just started and running..

Konsole-15.08

In KDE5: If I make many connection by ssh and live konsole to the night, at
morning it hangs, absolutely.
