Comment 8 for bug 1452318

In case it's worth anything, the following may help to diagnose the problem.

When I resume from suspend and lose desktop icons, panel icons, and random bits of text, I find that starting google chrome (or even just changing tab in an already open browser) will allow the screen to redraw when I move the mouse over the affected areas. I presume this is because chrome is using the acceleration.

Anyway, if someone who knows about this kind of stuff could take a look at it, I'd be very grateful.
