Hi, sorry nobody's got back to you about this before now. I can't reproduce in Emacs 25+. I think it's probably been fixed at some point.

Can you = reproduce this problem? I use clang version 500.2.75 from xcode 5 and = osx 10.8.5. I don't know what the above code does, but I hope it helps = finding the cause of the problem. I was advised by Jan Dj=E4rv that setting the font-backend frame = parameter to "ns" also corrects the display problem. Many thanks.
