Can you retest with 10.1-1? It's in koji
Created attachment 871980 [details] Screenshot mesa-10.1-1.20140305 solves the laggyness and seems also the flashy corruption, but there still is some static corruption, i.e. in thunderbird some text and some pixmaps are white (see screenshot).
Flashy corruption just started happening again after panning around a while in google maps.
Seems fixed.
Actually, no, issue came back after suspend/resume. Reopening.
Seems to work for good now.
