            Bug ID: 109332
           Summary: xf86-video-amdgpu - commit 0d60233d introduced
                    stuttering with mouse cursor operations
           Product: xorg
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/AMDgpu

Originally reported inside this ticket:


There is stuttering caused by certain mouse cursor operations. To reproduce,
e.g. do this:

-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
