Hello, has anybody the same slow and choppy scrolling issue under Firefox3 with XWiki? Apparently this is linked to the fixed CSS background for the header menu... It doesn't appear on all hardware/OS configurations but lots of people complain about it. As XWiki uses a fixed background by default, I preferred warning you because this is really a pain using xwiki under FF3 on my computer :) (if you remove the "fixed" CSS field, it works betteeeeeeeer)
Works fine for me with FF3 on a Mac.
Who has this problem?
Me. It's not caused by one piece of software, but by a combination of elements. For example, using the open source Mesa driver is way slower than using proprietary drivers from NVidia or ATI, and the intel driver doesn't show slow downs at all. It's much worse on Ubuntu than on Gentoo. On Opera it is perfect, regardless of the environment. I'm also annoyed by this, and was planning to investigate this further to see if anything fixed causes slowdowns, or it's also triggered by the kind of image (png, with or without transparency). I'm saying this because Albatross is faster, and it also has the fixed menu, but with different images. -- Sergiu Dumitriu http://purl.org/net/sergiu/
