other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org  
mailing list.

Please give this e-mail an appropriate subject line!

Please describe exactly what actions triggered the bug and the  
precise symptoms of the bug:


An issue I've run into when upgrading to Tiger is that setting the  
frame font to e.g.
     -apple-andale mono-medium-r-normal--13-130-75-75-m-0-mac-roman
results in what looks like miscalculation of rendered string lengths,  
since moving the cursor over text, or scrolling, changes text width,  
leaving garbage all over the frame.Any ideas?  Under Panther this  
wasn't problematic, and -apple-andale mono-medium-r- 
normal--12-0-75-75-m-0-mac-roman works without issues.
