Probably fixed with Plasma 5.27 which included major multi-monitor fixes. If
you upgrade to 5.27 and find that it's not fixed yet, please feel free to
re-open this bug report. Thanks!

I still have the problem with current plasmashell 5.24.7.

Still now, I lose all taskbar items from time to time when using a
multi-monitor setup. Restarting plasmashell solves the issue temporarily.

I'm afraid Plasma 5.18 is no longer a supported LTS version. Please upgrade and
try again at least with Plasma 5.24, ideally 5.25 or 5.26.

This bug and bug 387901 are totally unrelated. Moreover I'm still experiencing
the bug very often.

When I disconnect the external monitor the plasma task manager does not show
running tasks on any monitor, like described in the original report.

I am seeing the same issue on git master with the icon-only task manager
configured to only show applications in current screen.

Disconnecting my external screens does not reset the task manager state and I
have to restart plasmashell as a workaround.

I believe issues bug 387901 and bug 391033 are reporting similar simptoms that
could be cause by the same issue.

I'm seeing this multimonitor bugs since at least August, 2017(I know, I should
have filed a bug earlier but life... :) ), on a Arch install on my Dell E6400.
I was hopping that Plasma 5.13 would resolve this but it only seems to
attenuate a little bit.

At the moment, my main laptop (Dell E6230 with dock) is on Fedora 28 with
Plasma 5.13 and I'm still seeing similar issues.

The "missing" applications seems to be more localized when I close the lid of
the laptop while the external monitor is connected.

If I undock the laptop(with lid open to keep the laptop to suspend), all
applications are visible in task manager.
Docking again, all aplications on external monitor, are now visible in task
manager.
If I want to have the lid closed while docked and applications showing
correctly, I use the workaround "kquitapp5 plasmashell && plasmashell". This
make the applications to reappear in the task manager.

It sometime happens when I've turn off monitor while lid is closed(laptop
suspends) and I resume from suspend undocked, but I cannot reproduce everytime.

I noticed that a file with suffix _lidOpened is created in
~/.local/share/kscreen, when I close the lid(while docked and external monitor
connected), and the file is removed when lid is reopened, while in the dock.
The _lidOpened file is not deleted when I've turn off monitor while lid is
closed(laptop suspends) and I resume from suspend undocked.

Not sure if related, but I see 5 different panel ids configured in cat
~/.config/plasmashellrc, when I only use 2 panels.
When I remove the panels, they are not removed from the config file.
If I move a panel to another position on the same or other monitor, the
previous configuration is not removed. Sometimes, the configuration is not
correct, for example, showing a horizontal panel as vertical and incorrect
resolution.
Also, if you manually remove a panel from the config, it will not reappear on
the config after laptop restart or plasmashell restart.
I deleted ~/.config/plasmashellrc, restarted plasmashell, created new panels
and moved the panels to its final position to have a cleaner config file but
task manager still have the same behaviour.

My normal setup is:
Laptop screen only: Default Panel with only filter "show only windows from
current screen" enabled.
Laptop and External monitor: 
  * Laptop on the left side: Left Vertical Empty Panel with Icons Only and with
only filter "show only windows from current screen" enabled.
  * External screen on the Right side: Bottom Horizontal Default Panel with
only filter "show only windows from current screen" enabled.

External monitor is connected to the dock using direct (no adaptador of any
sort) DisplayPort-DisplayPort cable. I will try to change my setup to use a
DVI-DVI and see if there is any changes.

Attached kscreen and plasmashellrc config files.

I know this comment is long and apologies if its not very clear.

If someone has more information on how to troubleshoot this further let me
know.

Hello,

I'm having something like this problem. I use task manager configured to show
only windows in the current monitor. I'm using 5.13.3 (openSUSE Tumbleweed)

My second screen sometimes does not recovery nicely from sleep/hibernate or
from power save mode. The screen becomes either off (but KDE still detects it
as on) or shows garbage. My workaround is to turn it off and on again:

 xrandr --output DisplayPort-0 --off
 xrandr --output DisplayPort-0 --auto
 xrandr --output DisplayPort-0 --rotate left --left-of DisplayPort-1
 xrandr --output DisplayPort-1 --primary --pos 900x131

When I do that, plasma task manager losses the association of windows-screen on
the primary screen, showing no window at all. The secondary screen does work as
expected.

If I create a new task manager, I can see the correct list of windows.

If I uncheck the "show only windows from current monitor", I can see all
windows, including from the primary screen. However, if I mark it again, I
return to the problematic state.

If I restart plasma, everything is back to normal.

Is there any info to get while the problem is happening?

If there's any chance you can upgrade to a more recent version of Plasma,
please do so and try to reproduce. There have been a lot of multi-monitor and
Task Manager improvements since 5.8.6.
