thanks for the three patches, the high-level ideas what they do seem
patch 1: I'd have to take a look if that is the right place to do it,
or is it just an ad hoc band-aid and would be better fixed in some
other way in a more "once and for all" solution.
patch 2: looks good.
patch 3: Wasn't there a more modern way of doing this instead of
abusing XWarpPointer? Something about maybe XI2 delivering relative
I also wonder, if Weston is fullscreen and something else like a
notification pops up in a corner, is it possible for the user to go
and click the notification?
I suspect we would need to pass through the pointer confinement
protocol to be able to make things behave by end user expectations,
since x11-backend cannot keep on delivering relative motion if the
pointer hits an edge in the X server, but without pointer confinement
the user actually expects to hit an edge and/or be able to click other
I have noticed myself, that when Weston/x11 starts, the initial pointer
position in Weston vs. the X server does not match. If you wanted to
fix that only, then I think some fix to init the pointer position from
X11 instead of hardcoded should be enough.
If you want to revise these, please submit them via Gitlab.
