Hello I am reporting that I am having severe graphic issues starting from (standard) kernel 6.11.2. What I am having is a very laggy/stuttering display, especially the external one. You can feel it as soon as you launch the terminal, and it’s so bad to be unusable apart from debugging purposes.
Few extra considerations:
it only affects wayland (both Hyprland / Sway) and not X (i3 is fine)
it only affects kernel 6.11.2 onward (6.11.4 is still affected). The latest LTS (6.6.57) is fine.
Is this happening in casual desktop usaage or with gaming? We’re seeing folks on Arch (same kernel) having flickering during gaming, fine on older kernels.
Vanilla GNOME on Wayland Fedora 40 here, no issues (13 inch 7840U).
I do have another occasional bug that others have encountered too:
but that seems different.
Is that a “required” step to get the bug? If so which terminal?
I can’t find it now, but I vaguely remember a bug that involved the terminal emulator. I think I was running on X back then. CPU use high and/or display lag was involved. Shot in the dark but worth a mention.
Hi. I had similar issue on Manjaro (Arch based) with 6.11.3 onwards. It’s still present on 6.12rc4.
I resolved it with the following entry in /etc/environment:
On a FW16. No dGPU. Ubuntu 24.04.1 LTS.
I am seeing similar stuttering on mainline kernel 6.11.5 (not reproducible here in 6.11.2)
Playing videos in windows or fullscreen in youtube / firefox seems to be fine (plays ok).
When I use the linux application “mpv” to play a video, it plays ok in a window, but then tends to suffer or completely pause when full screen. Moving the finger across the touchpad advances the video almost frame by frame. Pressing keys (does nothing) does not advance the video.
Summary:
mpv plays well in 6.11.2
mpv pauses / stutters in 6.11.5
Is this linked to:
Using “xrandr --output eDP --set TearFree on” helps cure the problem for me.
I was seeing this as well since 6.11.2 or so on both FW13 11th gen and 13th gen. Definitely affected Hyprland, even with no GTK based apps running at all.
6.11.5 seems to be slightly less bad, but not completely cured.
EDIT: I’m changing my answer on this. Still getting stuttering and freeze ups, less so in the terminal but Steam games via proton are way worse.
