<pre>Applying this MR and disabling HW cursor "fixes" the mouse skipping in the menu
of Hitman 2 (as there is a cursor visible and thus pageflipping is turned off):
<a href="https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/merge_requests/38">https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/merge_requests/38</a>
But in the actual game, there is no cursor visible and so there is severe
stutter again.
I also reported the bug to the wine devs (still I think this is rather a bug of
xf86-video-amdgpu):
<a href="https://bugs.winehq.org/show_bug.cgi?id=47428">https://bugs.winehq.org/show_bug.cgi?id=47428</a>
There I mentioned that setting "MouseWarpOverride = disable" (a wine features
to work around/solve mouse issues) fixes the problem for wined3d/gallium nine.
However, it does not fix the issue in Hitman 2.
The issue in Hitman 2 also is a bit different, as it doesn't seem to have
slowdowns regarding the rendering performance, but instead the mouse input
rather seems to be partially blocked or discarded. But again: This does not
occur without xf86-video-amdgpu or amdgpu.dc=1.</pre>
