Given the length of time this has been a problem, I can't help wondering if
you've investigated any other solutions, such as ignoring XOR mode entirely
and doing it yourself on buffered images.

Of course, the viability of any alternatives will ultimately depend on
speed, but if Apple seems unable to remedy the situation in a timely way,
the only solution I can see is to eliminate the dependence and create your
own remedy. One advantage is that you can control exactly what appears,
regardless of what Apple does (or doesn't do) and when. If you control the
option of YourRemedy vs. XOR with a property, then you can easily switch to
XOR mode (or your customers can) at some future point when Apple fixes the
XOR problem.

I fully realize that "you shouldn't have to do this". But if you are
stumbling over a bug that's not getting fixed, your only choices are:
1) avoid it with a workaround,
2) eliminate it with your own remedy,
3) complain about it while doing nothing.

These choices are true for all bugs, in all software. As a developer, you
at least have the power to make a development decision (create a remedy or
workaround), rather than just act as a consumer and only make a purchasing
decision.
