Red Hat Bugzilla – Bug 187531
Poor redraw performance with GNOME apps
Last modified: 2008-05-06 11:43:44 EDT
Machine is an Athlon XP2000+ with a Matrox G550 graphics card (using the drivers
supplied by the standard rpm). The machine used to run FC4 and was recently
upgraded to FC5. After the upgrade, the performance went from respectable to
abysmal when used with GTK/GNOME applications.
A particular victim of the slowdown was Firefox... but most of the problems were
cured when it was started with MOZ_DISABLE_PANGO=1. GNOME applications cannot be
cured of this problem so easily.
Non-GTK applications such as nedit or lyx-qt do not appear to be affected. I
assume (perhaps wrongly) that this is related to the introduction of Cairo and a
regression in the support for a previously well-supported card with Free drivers
-- but since I do not know this for sure, I can only register it as a GTK problem.
