Thus spake wtfpwndd:
I do have a Retina display. I think you figured it out. I changed the
zoom to 50% maximum size and it works!
That’s not “working” if it doesn’t display properly at all zoom levels.
The probelm you’re having is the one described on this thread:
Missing Card Text, Glitchy maps
I haven’t had time yet to find a workaround for the bug that Java
has w/r/t painting images on Retina displays, but it’s on my list.
