[Mesa-dev] [PATCH 0/3] Fix vmware dri3 latency on gnome-shell

[Thomas Hellstrom]

Similarly to what we previously did for GLX_OML_sync_control, we want to
disable the GLX_SGI_video_sync extension for gnome-shell on vmware. With
either of these extensions enabled, window movement lag increases
significantly.

The reason this hits with dri3 and not with dri2 is that with dri2 on
xf86-video-vmware, this extension is enabled, although not fully implemented.
With dri3 we actually sync to the X server's built in fake 60Hz vblank
interval.
