--- Comment #7 from Jan Beich <jbeich at FreeBSD.org> ---
(In reply to pete from comment #6)
modesetting(4x) is slightly slower than SNA from xf86-video-intel and is part
of xorg-server which haven't been updated for years. Let's ignore those.

My main gripe with modesetting(4x) is stutter and sometimes flickering on
redrawing GL applications. As I use multimedia/mpv on a separate workspace
modesetting(4x) causes A/V desync almost always. Quickly switching to/from a
workspace with glxgears archieves the same effect. Obviously, Wayland (Sway) is
not affected.

Changing drm-kmod version to 4.20, 4.16, 4.11 or 4.9 doesn't help. I'm on
Skylake and suspect Intel may have ironed out modesetting(4x) support in later
iGPUs e.g., Icelake won't support legacy drivers (xf86-video-intel or
libva-intel-driver).
