Then you just have to avoid moving another window on top of the browser window, as there are no independent wi= ndow layers without compositor. But yes, there are red spikes of the "inter-frame (green/red) right scale" = with amdgpu.dc=3D1, while there are non with amdgpu.dc=3D0 (TearFree however doe= sn't work well in general without amdgpu.dc=3D1).

Well, there's no compositor to blame, as the issue also occurs=
 with just
TearFree enabled without any compositor. Then you just have to avoid moving
another window on top of the browser window, as there are no independent wi=
ndow
layers without compositor.
But yes, there are red spikes of the "inter-frame (green/red) right sc=
ale" with
amdgpu.dc=3D1, while there are non with amdgpu.dc=3D0 (TearFree however doe=
sn't
work well in general without amdgpu.dc=3D1).
I can also reproduce the issue with mpv playing a video, instead of a
webrowser. It stutters the same when doing the "clicky window moving&q=
uot; described
above.

Attaching recent dmesg and xorg log.
