The patch was abandoned upstream, but also was limiting the compositor refresh rate (not the mouse cursor) to 60Hz. That particularly annoys owners of 120/144/240Hz monitors.
Note this fixes Xorg sessions only. Wayland sessions have never run above 60Hz and require an additional fix from upstream coming soon (mutter!171).
