Running RetroArch on Wayland compositors (Weston, Sway, tinywl) I found out that the cursor gets sticky when it gets to the edges of the visible area.
That’s because the pointer coordinates are NOT confined to the visible area.
zwp_pointer_constraints_v1_confine_pointer() would be used for pointer confination on the visible area, like libSDL2 does on it’s
Wayland_input_confine_pointer function here:
…But I don’t even see if/where RetroArch should be trying to confine it’s pointer. There’s not even mention of cursor confination on the Wayland input driver code. Also, I can’t see “wayland” as a selectable input driver in RetroArch, but input/drivers/wayland_input.c is being built.
This seems to affect dosbox-core, too.
