GNOME extremely laggy (basically unusable) on amdgpu unless AccelMethod is None

[neelchauhan]

Describe the bug

Certain apps like GNOME and Wine 3D extremely laggy (basically unusable) on amdgpu unless AccelMethod is None in xorg.conf. In short, GNOME takes a while to load when it shouldn't.

DRM KMOD version

drm-devel-kmod 5.5.19.g20210909

This also happens on drm-kmod 5.4 and 5.6-wip, on both HP and Gateway laptops.

To Reproduce

Take an amdgpu-based PC, and install GNOME. You need to use gnome-shell in .xinitrc or .xsession as gdm isn't working correctly as of now.

You will see extreme lag where GNOME is unusable. Other desktops like KDE5/KF5 and XFCE4 work fine.

Screenshots

N/A

Additional context

I am using a HP Envy 13-ay0021nr. This also happened on a Gateway laptop using amdgpu (forgot which model).

This also happens on OpenBSD, but does not happen on Fedora (I believe 34).

[evadot]

Is that when using xf86-video-amdgpu ? Could you test mesa-devel too, that could be mesa-related.

[evadot]

This could also be something like https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251836 where we don't support some stuff and mesa fallback to llvmpipe.

[evadot]

Is it still happening with latest drm-kmod ? Also you could test https://reviews.freebsd.org/D35269

[grahamperrin]

Also, FreeBSD bug 257810 – x11/gnome3(-lite) & x11/gdm lags significantly on amdgpu (possible duplicate of 253746).

Closing as no news from OP.
