--- Comment #7 from Lamarque V. Souza <lamar...@kde.org> --- (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.
