Calling LockPortBits did it!
After reading the documentation for LockPortBits a long time ago, I
thought that it was not necessary to call this function when using
Quickdraw or Quartz and didn't care about it any more. Calls to
PaintRect and others seemed to confirm this. But the exception proves
the rule, this is not the case for CopyBits.

It would appear then, that I was wrong. I'm glad that you found a
solution!

I still suspect your real bug is elsewhere, and that this is masking the problem.
But I can't help without seeing your whole source :)
