Hi Mathias, I have had a look at the revision and vaguely remember hunting double a long time troublesome bug, but can't recall the details of the recreating the bug off hand. I'd have to look up what stuff I was doing around March this year. The r14805 commit message was "Fixed resize dimensions of X11 window".
At a guess, perhaps we can just do this check when we suspect a resize. What are the event times you are seeing? What platform are you testing on? Robert.
