Description marco.magliona 2024-03-27 14:09:20 UTC

Application: plasmashell (6.0.2)

Qt Version: 6.6.2
Frameworks Version: 6.0.0
Operating System: Linux 6.8.1-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 6.0.2 [CoredumpBackend]

-- Information about the crash:
While "scrolling" with the mouse on top of a grouped task in the task manager widget in the panel, plasma shell crashed completely.
The "preview when hovering" of the task manager stayed visible until the restart of plasma.
I cannot reproduce it anymore. Tried multiple times.
I had a similar crash while moving through windows, but I do not remember what I was doing more in detail.

The crash does not seem to be reproducible.

I can't reproduce this either on Plasma 6.1

Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.80
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.1
Kernel Version: 6.8.11-300.fc40.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 3600 6-Core Processor
Memory: 15.5 GiB of RAM
Graphics Processor: AMD Radeon RX 6600

However, do you remember what application it was that you were scrolling over?

I usually have a couple of Clion windows opened and it was quite glitchy before (I used to have this https://bugs.kde.org/show_bug.cgi?id=483162, https://youtrack.jetbrains.com/issue/JBR-6921/Plasma-6-Cannot-click-on-one-IDE-instance-when-a-second-one-is-running).
I think it was Clion, since minimizing and switching windows with scrolling would kind of momentary "fix" with the old bugs above.
I've updated Plasma soon after this report and I've not seen any more occurrences.

I'm setting this as fixed, since it seems to work for you now. If it reoccurs, feel free to open this bug report again :) Thanks!
