The background of the top toolbar (with back, fwd, etc) buttons becomes overwritten with garbage on screen redraws, or if screen is covered by another window. The buttons that are active are redrawn properly - those that are inactive have garbage written over them.

sjburges@gimp.org: Please follow the bug reporting guidleines available on: http://www.mozilla.org/quality/bug-writing-guidelines.html At a guess though, I think that this is a dup of bug 20496 which has been fixed. I won't know without more information though...

Yes. This was fixed some time ago. *** This bug has been marked as a duplicate of 20496 ***
