[kwin] [Bug 480367] Desktop sluggish/laggy after resume from suspend
https://bugs.kde.org/show_bug.cgi?id=480367 --- Comment #6 from Marcel Hasler --- I investigated this issue a bit further and at least in my case, running under X11, it turned out to be related to TearFree rendering. Without any custom configuration in place, i.e. 'xrandr --props' reports 'TearFree: auto', I get the behavior as described above. As I understand it, since I don't have any scaling or rotation enabled, this means TearFree is actually disabled. If I temporarily enable TearFree with 'xrandr --output eDP --set TearFree on', the problem goes away immediately and the FPS counter shows approx. 120 Hz, as expected. If I disable it again the problem returns just as before with the FPS capped to 60 Hz. What's even stranger is that if I suspend my laptop just once with TearFree on, the problem goes away permanently, even if I then disable it again, at least until I log out and back in. So the solution for me is to enable TearFree permanently by creating a configuration file /etc/X11/xorg.conf.d/20-amdgpu.conf with 'Option "TearFree" "true"'. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480367 Marcel Hasler changed: What|Removed |Added CC||mahas...@gmail.com --- Comment #2 from Marcel Hasler --- Same here on a Ryzen 7 7840HS / Radeon 780M. Simply restarting compositing by hitting ALT+SHIFT+F12 twice makes thing work again as expected. This is on X11. I have a 120 Hz display. Looking at the FPS counter I normally see a refresh rate between 100-115 (which I know shouldn't be considered reliable). After waking from suspend the counter is stuck at 60 and all animations/movements are slow and jerky. 3D apps like glxgears still report 120 FPS, though. I have also tried setting the display to 60 Hz but get the same result, just with the counter stuck at 30. I also tried uninstalling xf86-video-amdgpu and using the modesetting driver instead, but that makes no difference. I'll attach my KWin/X11 info. -- You are receiving this mail because: You are watching all bug changes.
