There was an update to Gtk+ today (from 2.16.6 to 2.18.3). After
performing the update, Firefox (3.5.4) is slow as molasses when
scrolling in some pages. Example:


http://www.simplemachines.org

(Try to scroll up/down).

Anyone else noticing this or is it just me? I'm on AMD64. I've rebuilt
xulrunner and Firefox after the Gtk+ update just in case, but it didn't
make any difference.

I forgot to mention that the problem is only really apparent with
"smooth scrolling" enabled (Preferences->Advanced->Use smooth
scrolling). It was a bit slow before the update too, but nothing
serious, but now it's *extremely* slow.

scrolls without any lag. Instant response. No lag at all.
Even with effects turned on there is no lag.

'sanften Bildlauf aktivieren'? Turned it on, restarted firefox. There is a
short jerk when scrolling the page for the first time but after that everything
is quick.
