Journalctl log of the crash

SUMMARY

Device 1: Opensuse Tumbleweed with KDE (and latest updates).
Device 2: Windows device

I switch between two devices using an external KVM. While firefox was open I switched from device 1 to device 2 using the KVM switch. After switching back to device 1, both firefox and plasmashell crash.

Firefox crash report: https://crash-stats.mozilla.org/report/index/1adc08c6-0dab-49f4-9ff6-17a420250819

STEPS TO REPRODUCE
1.  Open firefox 142.
2.  Switch to second device using KVM switch.
3.  Switch back to first device with KDE and firefox + kwin will crash.

OBSERVED RESULT

Firefox and kwin crash after going back to device 1.

EXPECTED RESULT

Nothing crashes when switching between devices using a KVM.


SOFTWARE/OS VERSIONS

Operating System: openSUSE Tumbleweed 20250825
KDE Plasma Version: 6.4.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.1
Kernel Version: 6.16.1-1-default (64-bit)
Graphics Platform: Wayland
Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor
Memory: 32 GiB of RAM (31.3 GiB usable)
Graphics Processor: AMD Radeon RX 6800 XT

ADDITIONAL INFORMATION

- This started happening after firefox 142. Firefox 141.0.3 works fine without any crahes.
- Firefox 142 does not crash when using Gnome. I tested this while booting into a Fedora 42 Live USB.
- Fedora 42 KDE shows similar behaviour to Tumbleweed KDE. Crashes happen in both.
- The crash only happens when firefox is using wayland. Starting firefox in x11 does not result in any crahes.

- I've already reported this to firefox, https://bugzilla.mozilla.org/show_bug.cgi?id=1983973#c1, I was told to post the bug here as well as this could be KDE related.
Comment 1 David Edmundson 2025-08-26 22:09:17 UTC 
Crash is ourside, you can close the firefox one.

Fixed by https://invent.kde.org/plasma/kwin/-/merge_requests/8029 which is backported to the next 6.4.x
