i added barriers. these are xserver-side barriers to thee mouse moving across
that boundary:

https://git.enlightenment.org/enlightenment/efl/src/branch/master/src/lib/ecore_x/ecore_x_fixes.c#L461

your video shows the mouse getting stuck at a barrier at the start ... then
just all of a sudden that stops working for some reason. e sets up the barriers
when it reconfigures the screen with xrandr. e in git now will also try use the
xrandr cmdline to do this too if there which handles barriers on its own.

i may have messed up the rect math. can you try apply this patch (attached) to
efl and see if it fixes it.
