I reported #894083 but I think it's a duplicate of this.
I find turning off compiz, or setting 'compiz>general>force full screen redraws' works around this issue, but they're neither ideal.
'Fix screen updates in XGL with fglrx' significantly reduces the frequency with which I experience this, but doesn't resolve it.
