Comment 17 for bug 278112

Thanks Dan,

That workaround definitely has something to do with this problem. It seems to have solved the problem here. "Seems" because, I'm only getting a dark screen, not the actual screensaver I've chosen, but that's probably a different problem.

Unredirecting full screen might not be the thing we want though, but I guess this takes us closer to the core of the problem.
