SUMMARY Recent Plasma Wayland from git has been freezing often for me, and I think it's happening when hovering panel thumbnails, as often the freeze happens precisely when the thumbnail appears, but without content in it. It's a complete freeze of the system, I can't enter input, move the mouse or change to a TTY, and if it stays long enough, it doesn't even send information to the monitor. Had to forcefully shutdown via the button on my laptop. The only useful information I can find is the following to errors (--priority err) in journalctl: kwin_wayland[2240]: kwin_wayland_drm: an error occurred while swapping buffers "EGL_BAD_SURFACE" kwin_wayland[2240]: kscreenlocker: Greeter Process not available I haven't checked if it's actually crashing yet, I didn't have coredumpctl installed. I'll be checking for more information this week. What should I use to provide better information for this? Operating System: openSUSE Tumbleweed 20220312 KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.2 Kernel Version: 5.16.11-1-default (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i7-5500U CPU @ 2.40GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 5500
Correction: it does let me switch to a TTY. The only error I see when switching to it, logging in and inspecting journalctl is the EGL_BAD_SURFACE one. Also, now that I tried, moving the mouse constantly does seem to flicker it, even if it doesn't actually move. And yeah, it's definitely 100% occurring when hovering panel thumbnails, but only when it fails to fetch the contents. Sometimes it works fine, namely when the contents are fetched correctly.
Hmm, this might be related to pipewire (seeing as the panel thumbnails use that). If it helps, my current version is 0.3.48 and I have wireplumber 0.4.8. I get the exact same freeze with the exact same error message when attempting to share a window on OBS Studio 27.2.3. Sharing a screen works fine, though.
Is this still happening? I think you were affected by the commit https://invent.kde.org/plasma/kwin/-/merge_requests/2145 fixed
The OBS window capturing and the panel thumbnails issue seems to be gone, but I did experience a freeze with overview that might or might not be related, as it didn't seem to produce the same error in journalctl. I'll test for a few more days and see if I can reproduce it still.
This is no longer reproducible for me. Thank you.
