FWIW, and apologies if you've already noticed this, but on my Mac I
can see it drawing a white hollow box cursor on the second frame when
the first frame is selected. I can see it overlapping some of the
characters.

Is it possible you're seeing a white box cursor with white text
instead of a black box cursor with white text?

A little git archaeology shows that the colour handling used to be a
lot more complicated, but it was simplified some time ago. I don't
understand what the old code was doing, and colour handling on the NS
port was always a little different for some reason...
