Assertion failure in confined_pointer_grab_pointer_motion
I encountered the following assertion failure while playing with Wine Wayland under Weston 11.0.0, nested under X11 with two virtual screens:
weston: ../libweston/input.c:4771: confined_pointer_grab_pointer_motion: Assertion 'pointer->focus->surface == constraint->surface' failed.
I haven't been able to reproduce this yet, I will update when I have more info.
