Subject: bug#11721: 24.1; Rendering bug in 24.x on OS X

I've seen this same behavior (duplicated pixels from menu bar) with an older iMac, but not a more recent MacBook Pro.

The iMac that shows the problem is:

  20" Mid 2007
  ATI Radeon HD 2600 Pro 256 MB

The MacBook Pro that works without issue is:

  15" Late 2011
  AMD Radeon HD 6750M or 6770M and Intel HD Graphics 3000

I was wondering if the graphics card might be part of the problem, but that is just a guess.

Both machines were running Mac OS X 10.7.4.
