I've always asked myself why Firefox on Linux feels so weird on certain websites. Just load up http://www.linuxactionshow.com/ and scroll with your mouse wheel. Can you feel the jerkiness? This is not fixed in Firefox 3 Alpha 5. And by the way.. I first thought this might be problem of the Gecko engine, but Opera has the same problem.. The site is smooth when using Firefox under Windows.

Another thing: Opening a new tab in Firefox 2 gives you a little retarded half-second "flash". The same can be observed when opening a new tab in the Gnome terminal. This is only partly fixed in Firefox 3 (happens for the first new tab you open, but not for the third, fourth, and so on.., but when you close all tabs and only got one window open and open a new tab it "flashes" again). This does not happen on Windows. Does anyone have an idea what might cause this? For me this is really ugly and if you use your browser several hours a day like I do, the "little things" can get pretty annoying :-(

The jerkiness is because the background image is fixed. The rest of the document can't be rendered off-screen for quick scrolling because the position of the background relative to the rest of the page (text, etc) is unknown untill the scrolling actually takes place.

The culprit is usually the background-attachment CSS property. Everybody should leave it at the default value of "scroll".
