That looks like a problem with your X11 server.  It works for me on X11 
on MacOS, and on the Cocoa display in MacOS, and in Windows.

I don't know much about what sorts of things go wrong with X11 servers, 
but a guess would be you don't have the right font installed so it 
doesn't know how to resize it.  I can't really help beyond that, e.g. to 
tell you how to figure out what was requested and what was delivered.
