I have the classic ati corruption lee and this is how it shows up:
1) it is fine moving the cursor over without painting. It seems to follow the surface correctly however the brush is slightly squashed.
2) when painting the cursor changes to BLI or something. It is in text and upside down. This is overlaid over the pink cursor.
3) the corruption is definately "trails" of this corrupted cursor image being spread all over the canvas.
I suspect incorrect texture format, or texture depth or something like that.
