Hmm, see if I could reproduce it consistently then we would have fixed
it by now.

I very occasionally see focus issues but generally it works and
especially when I just spend time flipping from one to another.

Maybe it's a race condition and your computer takes a long time to
redraw.  Is that possible?

Well I haven't reported it upstream as I've not been able to reproduce
it consistently myself.  I have seen occasional odd focussing but
nothing I can reproduce all the time.

That's the barrier to fixing it at the moment I'm afraid.
