Description nekonexus 2022-12-16 02:13:48 UTC 
Application: plasmashell (5.26.4)
 (Compiled from sources)
Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 6.0.8-272-tkg-pds x86_64
Windowing System: X11
Distribution: "Arch Linux"

-- Information about the crash:
What I was doing:

I had Steam already open, and I restarted Steam to install a Steam client update (unrelated to system package management; that's performed in $HOME), and while it did that I opened Yakuake to run "pacman -Syu" and then plasmashell crashed BEFORE I even confirmed any pacman updates; it crashed while I was in the middle of authenticating with "doas".

Signs of Unusal Behavior:

Nothing strange was noticible prior to this happening.

Non-default Configurations?

I have the compositor set to run with OpenGL 2 (KWIN_COMPOSE=O2), but that's it.

Additional Information:

This is about the second time I've had this happen this week but I don't know the exact cause of why this happens.

Additionally, for clarification, I use an x86-64-v3 Arch Linux repo: https://git.harting.dev/ALHP/ALHP.GO

The crash can be reproduced sometimes.

> I have the compositor set to run with OpenGL 2 (KWIN_COMPOSE=O2), but that's it.
Does it happen if you don't do this? Is there a particular reason why you're forcing this?

Also what GPU hardware do you have?
Comment 2 nekonexus 2023-01-05 04:46:41 UTC 
I don't exactly know what triggers it, so I can't exactly say if it happens without KWIN_COMPOSE being set with certainty since I don't even know how to reproduce it.

That said, I have it set because the KWIN_COMPOSE type used to be a drop-down customization option within systemsettings5 but was removed at some point (alongside with KWIN_COMPOSE=O3 to my understanding) and I missed being able to control this setting that was gutted from the compositing menu (it's not clear what its set to by default anymore).

Also, I use the Nvidia OpenGPU kernel module (version 525.60.11) on an RTX 2080 Ti.
Comment 3 Nate Graham 2023-01-05 15:13:03 UTC 
OpenGL 2 is no longer formally supported by KWin, so right now you're in unsupported territory. I would recommend reverting to the default OpenGL setting by removing that environment variable and seeing if it still happens.

If you can't use the default OpenGL setting for some reason, please file a bug about it. Thanks!

Comment 6 nekonexus 2023-02-04 09:16:37 UTC 
This is most certainly not resolved; there are plenty of reports for this (such as mine) with accompanying details for how to easily reproduce this.
Comment 7 nekonexus 2023-02-04 09:19:04 UTC 
Sorry about that, i got this issue confused with a different one

New crash information added by DrKonqi

plasmashell (5.27.0) using Qt 5.15.8

Plasmashell crashed when I closed a NoMachine window through the "icon task manager" widget on a panel. I couldn't reproduce the issue.

Comment 9 Riccardo Robecchi 2023-02-18 15:26:40 UTC 
Since this doesn't seem to be included in the information gathered by Dr. Konqi: I am using a laptop with an AMD Ryzen 2500U CPU, a Radeon Vega 8 GPU, X11 and default OpenGL.
