Could you please try the following? -disable Plasma compositing with Ctr + Alt + F12 (or in the compositor settings 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 release, 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=0 compton" to enable GLX compositing without vsync -now the repeatedly moving Dolphin's window procedure described above shouldn't lead to any stutter -when booting with amdgpu.dc=0, there also shouldn't be any stutter when vsync is kept enabled My layman impression is that this indicates the problem originating somewhere in the xorg/driver space, and not in Plasma or the compositor.
