[kwin] [Bug 447116] kwin crashes after pressing alt-tab twice
https://bugs.kde.org/show_bug.cgi?id=447116 andresdor...@gmail.com changed: What|Removed |Added Resolution|--- |FIXED Status|REOPENED|RESOLVED --- Comment #22 from andresdor...@gmail.com --- Tested for a week without https://github.com/catsout/wallpaper-engine-kde-plugin, and I think I found the culprit. It seems the issue is that catsout wallpaper engine plugin randomly crashes when plasma locks the session and when unlocked it loads in a broken state without hardware rendering (as denoted by the tray icon saying software rendering is being used and performance may be degraded) this in turn causes the task switcher to crash. To fix I need to remove the wallpaper source form `~/.config/plasma-org.kde.plasma.desktop-appletsrc` and then click on the tray icon that mentions software rendering and set it to hardware. The next time I start KDE, all is well, and I can set up wallper-engine again though it will cause the same breakage randomly when kde locks the session.

--- Comment #8 from Lamarque V. Souza ---
kwin_x11 also has this problem in my laptop when compositing is enabled. It was
disabled when I first tested, so I could not reproduce the problem. So both
kwin_x11 and kwin_wayland have this problem for me. The difference is that
kwin_x11 does not crash, it just disables compositing when the problem happens
('qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.active' returns
false). I have the re-enable compositing through systemsettings, using 'qdbus
org.kde.KWin /Compositor org.kde.kwin.Compositing.resume' does not work.

Souza --- (In reply to Vlad Zahorodnii from comment #6) > > shows that qmlscene uses the nvidia gpu in my wayland session > That's really strange. Both kwin and qt should use the same render device. I think that was because I was using nvidia-drivers-495.46 (this one uses gbm). I downgraded to nvidia-drivers-470.94, which seems a bit more stable and qmlscene shows it is using the Intel gpu. > > pressing ALT-TAB twice before the switching app is loaded will crash kwin > > and switch off composer > Just to clarify, should alt-tab be pressed twice before the task switcher > window is shown? I created this video to show that happens: https://photos.app.goo.gl/pEbGALMLLDkyZ7Zs9 Just one Alt+Tab is enough to crash kwin_wayland in my case. kwin_wayland restarts after the crash (ps shows there is a new kwin_wayland instance with different pid), but it get stuck somehow. The gray window that appears three times at the end of the video is me pressing Alt+Tab three times. It seems it tries to render the thumbnail switcher, kwin_wayland does not crash this time, but also does not render anything besides that window. I have to 'killall kwayland' to get a new login screen in sddm. -- You are receiving this mail because: You are watching all bug changes.
