[Bug 42825] Propellerhead Reason 5 drawn mostly in black and white

Thank you for the patch. This seems to have fixed the drawing being done in
black and white, but the visual glitches I mentioned are still there, now even
more prominent.

I've attached a screenshot and a compressed log of the Reason 5 demo playing
for a few seconds and as you can see, it's not a pretty sight. If I let it run
for a bit longer it seems to just give up, draws a mostly black window a
displays a message box saying it has run out of memory.

I have a feeling that this problem has also been caused by the changes to
BufferedPaint, but it is a different issue. Should I file a new bug?
