Bug 257810: x11/gnome3(-lite) & x11/gdm lags significantly on amdgpu

--- Description ---
On both an HP Envy x360 and a 11" Gateway laptop (2020, but forgot which model)
which both use amdgpu integrated graphics, GNOME lags significantly where it's
not usable.

This also happens on the Envy with OpenBSD, on both GNOME 3 and 40, unless I
use scfb. I don't know about Linux as I only booted non-GNOME-based distros via

This is an amdgpu problem with GNOME as KDE does not lag on the Envy, with also
being able to play Toontown Rewritten via the Linuxulator. I believe it's AMD
GPUs as scfb on the Envy and Ryzen desktops with Nvidia GPUs don't lag. I don't
know about discrete Radeon GPUs or the older radeonkms driver.
