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.
Also: this can be worked around by adding amdgpu.dcdebugmask=0x400 to your cmdline until the patches hit stable.
Although I’m unable to reproduce the issue (sway with 6.11.6, though I never had any issues with earlier kernel versions either). Might be related to Xorg/Xwayland, which I’m not using.
Well, GSK_RENDERER=ngl is not helping, while the “TearFree” issue is not applying since that refers to xorg (which in my case I remember was working) while I am on wayland (sway/hyprland suffer in the same way).
Not a kernel issue but a bug on gtk.
Not understanding this comment. I had highlighted that switching kernel version fixed (or hides?) the issue. Other libraries like GTK are the same.
But as I was mentioning that issue/fix was related to another bug (xorg, not wayland, at least reading the description). In fact, as an extra test, I have compiled today the Arch Linux kernel “linux-amd-staging-drm-next” and it does NOT solve the issue… I still only have ~10fps in the external display and ~42fps in the internal display.
Can confirm both 6.11.10-2 and 6.12.1-4 exhibit this issue.
6.10 was still fine, but since it’s now EOL, I had to downgrade to 6.6 LTS.
For me though, the external 1080p60Hz screen is not affected at all, but the internal one is, severely so (if I switch from 165Hz to 60Hz it’s basically freezing, it’s so bad).
Recording doesn’t show the issue, OBS on the external screen (internal one would make it unusable) recording the internal one shows no stuttering at 60fps recording even if what I am seeing is a slideshow.
I’m using a FW16 with 7840HS using the iGPU on wayland+KDE, and it’s definitely not gtk related as pure glfw+OpenGL applications are affected just the same as are KDE system interfaces.
Interestingly, Firefox and Thunderbird both are completely unaffected, but all flatpak+electron apps I have are.

This is a really interesting observation! I came here to report the same lag/stuttering issue, but I originally thought that it affected all applications. But as I type this in Firefox I am not experiencing the keyboard lag/stuttering to nearly the same degree that I do when in Chrome (or even in my terminal, foot). I do still occasionally see a lag/stutter, though, so I wouldn’t say it’s completely resolved in Firefox for me, but it’s still interesting that the application makes a difference at all.
While I tried I didn’t notice any stuttering in firefox at all (though I think at some point the hamburger menu of firefox did cause a stutter). I already switched back, but I could try more if anybody needs more info to debug.
Do you also have an external monitor to test with? Since OP actually experienced it MORE on their external one, and I did not at all, that seems like an interesting data point.
