I just figured out how to reproduce this on Windows - it seems like
VMware was confusing matters, but I can see the problem now. I'll
update the ticket.

BTW; whilst it won't affect the runtime titlebar etc. are you aware
you can use Ctrl+ (depending on your keyboard, you may need to hit
Shift as well to get Ctrl+ rather than Ctrl=) and Ctrl- to zoom the
display? That will allow you to get it to a usable size.
