This is actually because you can't overlay non-GL widgets over GL widgets.
This problem is related to the problem about switching between the GL
painting and the non-GL painting which I described in an earlier mail
to the mailing list (OpenGL Update). I don't know how to solve the
problem described in that mail.

It's still slower than it could be, however. There are a few changes
that could increase performance without much work; beyond that major
changes would be required.

Also, the GL painter doesn't work properly with star colours. This is
a (not trivial, but not very hard either) fixable regression; I have
an idea of how to fix it.

I'll try to get my computer into a workable state so I can help fix
things (this is, incidentally, why the merge was done by Akarsh and
not me) but I don't have much free time; this semester is a lot of
work.
