[Desktop-packages] [Bug 1982560] Re: Mouse lag/stutter (missed frames) in Wayland sessions
I tried the lines: MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 MUTTER_DEBUG_FORCE_KMS_MODE=simple in /etc/environment as suggested. It does not help. Or it did not help much. I think the keyboard lag might be less prevalent, but the mouse is still problematic. My symptoms remain the same: 1. everything is fine right after the window manager starts 2. After between 1 and 4 days (depending on usage), the mouse starts to skip and lag and stutter. During this condition, moving the mouse in small circles is enough to send 'gnome-shell' CPU use to 100% and cause updates to the display to stall or pause for long intervals, sometimes many seconds, until I take a break with the mouse movement -- for example Gnome System Monitor won't update its contents or rarely will, until I pause the mouse movement. I am using the integrated GPU on my laptop in this case (no discrete GPU, Ryzen 4750U processor). 'radontop' indicates about half of the 2GB memory reserved for the GPU is used, and GPU usage drops to 0% during the stalls. 3. If I log out of my user and log back in, everything is back to normal, for a few days. Switching to xorg fixes it (but causes other problems). I recently updated to 22.10 to see if that helped, it does not. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1982560 Title: Mouse lag/stutter (missed frames) in Wayland sessions Status in gnome-shell package in Ubuntu: Incomplete Bug description: Mouse lag on fresh install of ubuntu 22.04 LTS (wayland).
