Could you please try the following?
-disable Plasma compositing with Ctr + Alt + F12 (or in the compositor sett=
ings
and log out and in again)
-get the latest Compton release by yshui: https://github.com/yshui/compton
-start Compton (Mesa still enables vsync automatically in the latest releas=
e,
this has changed with compton-git)
-open a Dolphin window and www.vsynctester.com in webbrowser
-now click Dolphin's title bar, move it a bit, release it and repeat the
procedure several times in a row
-there should be stutter happening in the vsynctester.com browser window
-now quit Compton and start it with "vblank_mode=3D0 compton" to =
enable GLX
compositing without vsync
-now the repeatedly moving Dolphin's window procedure described above shoul=
dn't
lead to any stutter
-when booting with amdgpu.dc=3D0, there also shouldn't be any stutter when =
vsync
is kept enabled
My layman impression is that this indicates the problem originating somewhe=
re
in the xorg/driver space, and not in Plasma or the compositor.
