Comment 93 for bug 586325

I've now got a Q965 system to test locally, and my isn't this bug fun!

I've come to suspect that this might be a hardware-cursor issue. For me, when this bug gets triggered, moving the mouse up and down changes the piece of the framebuffer that's displayed, and moving the mouse left and right changes how fast it flickers - to the point where moving the mouse to a certain x-position results in a stable (albeit vertically shifted) display.

I'll test whether fiddling with this cursor code makes a difference.
