Photo showing the problem.

I see this with UMS on a R520, usually after watching some videos in YouTube.

Switching to console and back makes the glitches go away, so I tried to move the upload code to RADEONPutImageTextured() and make it execute once... that fixed the problem.

So my next guess was that something was overriding the bicubic memory, so I doubled it, and then the squares became more frequent.

Attached is a photo showing the problem.

Disregard that patch. Didn't work for other clips.
