It is fixed in latest Xorg. You will have to wait until Ubuntu LTS rolls out
the updates, or install from a backports repository.

The cruel truth is that the bug you saw was not a bug introduced by KDE
developers. Since it's resolved at the underlying packages, let's close it.

Well thanks to the Spectre flaw 16.04.x users (including kde neon) are getting
a new version of the kernel in the next day or so - at least those running the
hwe kernel - presently @ 4.10.x - we were getting 4.13.x anyway in Feb but this
has been sped up due to the issue.

Who knows this may fix the issue (I really doubt it however)

I can confirm that after upgrading my Kubuntu system from 17.04 to 17.10 the
problem is not happening.

I have to say that the real bug is/was never whatever they fixed. Honestly,
after all these, whatever it was doesn't really matter:

The real bug *IS the bad attitude* that _some_ (but an ever increasing number
too!) KDE devs have adopted as standard, that generate ultra-defensive replies
(if any at all). In some cases, it might not be bad personality or bad
character: It might be a worrying sign of something else altogether.

While I --having myself been victim of burnout like many others-- understand
the symptoms of that condition and how important it feels to kick out any
problems as small as they might be when you are in such condition, the cruel
truth is that until recognize and accept what you are going through, you are
just going to get worse. You'll find yourself raising your voice (or writing
all in caps) more often than you would normally do before, and failing to make
good decisions because frustration takes over the best of you.  With all
sincerity and good will, I strongly advise those who are felling like that, to
seek for professional help before it's too late.  For those who are just jerks,
I think they should abandon the FOSS community altogether.

I have been watching many threads in the KDE bug tracking and it's really scary
what I see. As user, I must say that this really is getting the prize of the
least friendly community and frankly the least helpful I have seen since a few
years already. Of course with honorable exceptions: those reading will know. If
not, please just spend a little more time reading through threads of this bug
tracking system or just try and open a new one yourself.

IMHO I think that the KDE project as a whole, should look at those devs that
are burned out or in their way to that: they should not be allowed to "help" in
this bug tracking system. I am not being sarcastic, I seriously mean that.

The next sentence _is_ sarcastic, but I hope it somehow helps to make this
dramatic point clear and no offence intended: To tell people that "this is not
a KDE problem go complain somewhere else", an automatic script would suffice,
no overwhelmed human needed.

I have discovered that Kubuntu 17.10 isn;t affected by this bug. 
Quite some time has passed since my last time checking on this bug. So I
decided to give Kubuntu and Kde Neon another go, since I heard there were some
updates and wanted to see how it works as I wanted to go back to 16.04 LTS but
both KDE Neon and Kubuntu 16.04 with latest greatest updates gave me the damned
cursor bug with Nvidia drivers. tried different version, no difference. Then I
thought what if it was kernel related, Kubuntu 17.10 comes with a newer kernel
which at the time was 4.13 so I upgraded my Kubuntu 16.04 to Linux Kernel 4.13
and the issue is still there. Again went through many recommended workarounds
and none seemed to be the good one. Went back to Kubuntu 17.10 again and have
no damned cursor bug. A good starting point too look at might be the
differences between Kubuntu 17.10 and Kubuntu 16.04  because Kubuntu 17.10
seems to have it solved for the users.

@Morgan Cox I didn't say it's a solution. It's another dirty workaround to
compensate a SDDM bug.
Turns out XRender compositing affects VLC too which is pretty bad.

Another 'workaround' is to use 'slim' instead of SDDM.

I thought about opening a ticket in the SDDM GitHub page...but they have 200+
open issues and doesn't seem they care that much. I think SDDM should be
abandoned for good.

And I do totally understand your comment about Linux newbies. At the moment I
don't feel suggesting Neon/Plasma to anyone either.

Thanks @Massimo Callegari


However using Xrender isn't really a good solution, really you are wasting your
GPU using that.

At least after sddm restart everything does work normally with full h/w
compositing.

This is a really annoying bug and I know for a fact it has caused friends who
wanted to try out neon to abandon it (some reinstalling Windows..)

For the sake of it, and since restarting SDDM every time is VERY annoying,
there's another workaround found here
https://bugs.launchpad.net/ubuntu/+sour ... ug/1684240 - #16

Go to KDE System Settings -> Display and Monitor -> Compositor (left side) ->
set "Rendering Backend" to XRender

This bug is still present.

If we are meant to be reporting this elsewhere can someone explain where ?

The bug is NOT only KDE Neon. It has been happening in Kubuntu ever since
upgrade to 17.04 and it was not because any nvidia upgrade. It remains exactly
the same today, with all possible ubuntu updates. Workaround: log out and login
again.

It is interesting that there are so many bug reports open for this bug in
bugs.kde.org (at the very least: 381533, 382865 and 382812) and it keeps being
pointed as "somebody else" problem, ranging from nvidia, KDE Neon, X11, etc.

It looks as if a normal user that just wants to switch on her KDE system and
sees that it won't work as advertised, only has the option to become a
developer in order to determine herself what exact line of code is broken,
instead of simply complaining to the KDE developers to figure it out
themselves.

It is very sad to see that users do not have the possibility of even just
reporting a problem without getting a finger "talk to somebody else, we don't
know". That's the point.

What do you do when you find a "bug" in your TV set: do you go to the vendor
and complain or do you start figuring out yourself every single possible
component of that system that could be failing to avoid the unpleasant response
"not our problem"?  Could you at least lead all the users in a decent direction
that doesn't involve quitting using KDE at all?

this is definitely not only KDE Neon specific, this issue takes place on I
guess every Ubuntu based OS that use KDE Plasma 5, I did a clean system
installation of KDE neon and got this issue, thinking it might be because of
KDE Neon I went back to Kubuntu 16.04 (also a fresh install) and the issue
appeared again when my system was enabled to use Nvidia instead of Intel card.
This annoying bug affect KDE users on various distro basis ( as seen mostly
Ubuntu based) and has something to do  with the latest updates (up until
writing of this comment), KDE Plasma 5 ( older and latest releases) and systems
with Nvidia cards ( as far as I was able to track).  Note that other DEs
doesn't seem to have this issue, KDE Plasma 5 developers should put some eyes
on this, we don;t want to see users not recommending Plasma 5, it is too
awesome to be ruined by something like this. It might look like a small issue
but it ruins the usability to the most common daily tasks, that is really not
good.

Do we need to open a bug report on ubuntu bug tracking for Xserver ?

Workaround would be to restart sddm twice on boot (not elegant)

Note that neon developers only maintain the KDE software, everything else,
including kernel and xorg, are used directly from Ubuntu.

Martin reassigned this to neon developers. Maybe they find a way to test Plasma
integration with proposed changes from Ubuntu before they hit the update
repositories.

When I boot from my previous kernel, 4.4, I have no mouse problems, even though
I am using the same nvidia 378 driver with 4.4 as is used with 4.8.  After I
boot into 4.4 I can do a warm reboot into my 4.8 kernel and the mouse continues
to work normally.  However, the workaround given by Cox, restarting sddm, is a
lot faster and works well.

Reassigning to neon: not a bug in KWin, users complain about the regresssions
