I have seen the diagonal tearing on just about every ATI/AMD graphics
chip I've ever tried. Though I only remember seeing it with fglrx, not
radeon. That strange diagonal tearing is certainly something you'll only
see with ATI/AMD graphics. It seems to be something to do with the ATI
hardware or driver architecture. But it's still possibly something we
can workaround in software...
Sorry, I don't know why the problem would take 5 minutes to come back.
Please try the workaround: In "ccsm", Workarounds, enable "Force full
screen redraw (buffer swap) on repaint".
