Package: firefox
Version: 1.5.dfsg+1.5.0.1-4
Severity: normal
After upgrading to firefox 1.5, scrolling became slow, sluggish and CPU
hungry.
For example, scrolling up and down http://gallery.menalto.com/ feels
dead slow and uses all the cycles of my poor 800mhz CPU...
Is it a gtk2.8+cairo or mozilla issue?

It does better rendering for non latin scripts, and does have not so bad
performance on most desktops. Since you can disable it at will, this is
not an issue.
Closing the bug.
