just as a note for people not following irc discussions [and also for
my bad memory :-) ], it got reported that while this seems to work
nice on wayland, X11 seems to have an issue with it, to quote from
the public log:
"hmm.. but something funky is going on. with your patch the curser doesn't
seem to be updated if i move it close to the left or right edges of the
screen if the slower i move the curser towards an edge the closer to the
edge it will draw the cursor removing your patch again fixes the problem
this is in plain old Xorg version 1.20.3"
