May I ask how you can work such magic from such a distance? Do you have similar hardware with which you can reproduce the bug, and then just make the bug go away on your hardware? Or do you know the code so well that you just make educated guesses about what might be the cause of the problem?
Another bug pointed to a similar issue beginning around the time I reworked the blit code, so I figured it was a likely candidate.
