Sysprof showed most of time is spent inside firefox/gecko, so I don't think this is a linux specific problem. Reproducible: Always Steps to Reproduce: 1. Open the page http://html5test.com/ 2. Scroll up and down 3. Actual Results: Scrolling is very slow, single-digit FPS scrolling animation Expected Results: fluent scrolling like in Konqueror or Opera
Confirmed with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.5pre) Gecko/20100522 Namoroka/3.6.5pre but it is improved with the latest trunk nightly build. http://nightly.mozilla.org/

It seems the official binaries use client-side gradients, even if there is a capable x-server used.
Looks like this is not a duplicate; that bug was fixed (on Windows) without affecting this bug (on Linux).

Seems to be fine on all three platforms here.

When I use the scroll-wheel everything is fine - however dragging the scrollbar makes scrolling very choppy and firefox consumes a huge amount of CPU cycles.

Still there with FF19 on Linux. Even on a high-end notebook powered by core-i7. The size of the FF window seems to have a lot of influence on scrolling speed, especially when the window is resized to full 1920x1280 scrolling starts slow down.
