I can confirm this on other sites. For example www.winsupersite.com. Scrolling even if not zoomed is very slow, much slower than in any other browser. When zoomed its almost unbareable how slow the scrolling is. It doesn’t matter what you are scrolling the page by (mouse wheel, dragging the scrollbar, arrow keys). I’ve been noticing this for long time in stable Firefox 3 and nothing has changed in oncoming Firefox 3.5.

I searched for similar bug reports and here are my findings: * Bug 479852 * Bug 480806 * Bug 425234 * Bug 426388 And here's another easy way to reproduce the problem: 1) Load your mailbox in Google Mail 2) Full-zoom to 200% 3) Enable the 'Tasks' labs feature 4) Login again to your GMail account with the 'Tasks' labs feature enabled. 5) Scroll now becomes seriously slow.

It really seems to have even worsen in 3.5 Beta in comparation with stable 3.0 version. Really nicely visible on the page I’ve already written about: www.winsupersite.com. In 3.5 Beta 4 it’s almost unbareable.

I see this also on Linux (however I can't update the platform field in this bug). Text zoom is fine. Page zoom at any value other than 100% renders some sites unusable. This did not occur with 3.0. I offer http://scienceblogs.com/pharyngula/ to the list of test cases.
Ok, maybe I will regret for that but I have to duplicate this one to a similar bug which has a minimized test case. Please don't spam the other bug with confirm comments.
