This is a long standing race condition with fltk, and I think it's the
biggest thing we have to fix before we switch the default plotting
engine from gnuplot to fltk. Known problem, also happens outside of
Windows.

No, it shouldn't. A stupid workaround is to insert pauses after each
fltk plotting command so as to probably avoid the race condition.

These two may be again more UB symptoms of the same race condition.
Does the stupid workaround described above also work on these?

I thought we had a report for the fltk race condition, but can't find
it. I think all we ever did was discuss it extensively in the mailing
list. If you can't find a report for it in the bug tracker, and if 3
and 4 are indeed also symptoms, it may be worthwhile reporting it.
