bug#3253: 23.0.92; Subpixel rendering slows down significantly

[Torsten Bronger]

When activating subpixel rendering under Gnome (Ubuntu 9.04), Emacs is slowed down significantly.  Scrolling through a large text file take 1.7 times longer than with "ordinary" anti-aliasing alone.

Is this still an issue with the latest version of Emacs?
Can anything actually be done about this?
