More agressive delay and retry after screen layout changed
We still sometimes end up with an improper layout after running xrandr
on X11 startup. I suspect this is a race condition between xrandr
setting the resolutions and scren geometry, and Qt receiving this event
too early, still omehow reading stale information when querying X for
the current setup. So we now wait 300ms instead of 100, and additionally
retry again after a second. If this doesn't fix the issues, the root
cause must be something else.
