I can confirm this behavior on Ubuntu 8.x with Firefox 3.0b5. For me, the slow scrolling seems to be limited to websites with a significant amount of CSS layout.
To test this, I have installed the Firefox Web Development Add-on which offers some tools to test out the CSS in a given page. With CSS turned on normally, the scrolling is really slow and very jerky. As soon as I disable all CSS parsing for the page, scrolling immediately improves to the way it should work. Smooth and fast. Compiz/Xgl does not seem to affect anything, whether I use the lowest Appearance settings or anything else. Disabling Pango does not have any effect either, The only improvement I get is by disabling CSS altogether. -- Very slow and jerky scroll renders browser useless https://bugs.launchpad.net/bugs/74116 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
