Description partain.m 2022-07-20 16:09:59 UTC 
Application: plasmashell (5.24.5)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.15.0-41-generic x86_64
Windowing System: X11
Distribution: Feren OS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I rebooted my laptop and closed the lid before it came up.
I rebooted my server with the tv it was connected to turned off.

In all cases, Plasma crashes every time.  Plasma does not crash if I reboot the laptop with the screen open or the server with the TV on and connected to its output.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted

Fix redundantoutputs when the enabled screens change very quickly

on X11, when a single transaction from KScreen disables screenA and
enabled screenB, a new output order arrivers before the old output gets removed
 and in that moment the new screen will be considered redundant to che screen
that is about to be removed, causing an invalid internal state

containmentview: Remove QueuedConnection from setContainment

Queued connection here causes a race condition when restarting plasmashell
and can cause it to get stuck to crash loop, since plasmashell
tries to assert for panel to be visible but this slot is not even called
yet, even though the signal is emitted.

Git commit b76440b35bb8c067731dfe30e888589ade90551f by Akseli Lahtinen.

containmentview: Remove QueuedConnection from setContainment

Queued connection here causes a race condition when restarting plasmashell
and can cause it to get stuck to crash loop, since plasmashell
tries to assert for panel to be visible but this slot is not even called
yet, even though the signal is emitted.

That commit made it into Plasma 6.0.5, which will be been released in about two weeks. We think this may have resolved the issue fully; closing the bug report. However please do feel free to re-open if if you can still reproduce the crash with 6.0.5 or later.

If you do, make sure it's the exact same crash, with the same backtrace.

Thanks!
