Pointer Warping Emulation Is Being Worked On For XWayland To Fix Games

WAYLAND --
While many games are running on Wayland either natively or through XWayland (the most likely scenario right now), not all of them offer a great experience due to functional issues. One of the functionality problems right now for games being piped through XWayland is the lack of pointer/mouse warping.

Wayland doesn't inherently support pointer warping -- or the centering of the pointer to the middle of the screen when starting the game -- and this can cause problems for some games, particularly shooters, with no warping. Jonas Ã…dahl has been working on pointer warp emulation in order to support such games with XWayland. With his experimental patches, games like Half-Life 2, Trine 1, and OpenTTD are behaving appropriately with this emulated warping.

Those wanting to learn more about this in-progress pointer warping emulation for XWayland can see this mailing list post with all of the technical details.
