Oh dear, this doesn't sound good.
The cynic in me suspects that the same Apple engineer who botched up
PostScript font rendering has been given the task of "improving"
TrueType font rendering.

The real problem is that OzTeX uses ancient QuickDraw calls to draw
characters from outline fonts.  Apple have deprecated QD and are no
longer willing to fix QD-related bugs, so we're stuck with these
sort of problems until I switch to Apple's newer ATSUI font calls.
That's quite a lot of work and I suspect it's never going to happen.
