Hi, A thing that I already recognized since a long time, but now it affects me more because I really start using xwiki in production, daily, and look more often in the documentation on the .org website: On Ubuntu Linux with firefox (3.0.6), the administration/navigation bar on top of every xwiki page is flickering a lot when scrolling hte page instead of just keep being there as it is probably intended. it keeps there in the end, but it flashes heavily, which makes me very nervous and is bad for the eyes. On my own site I change is by making albatross the default - here it works poerfectly as intended. The bar is always there but no flickering at all when scrolling. I see, the problem doiesn't happen with Opera on UBuntu so I can work around it, but sure I'd rather like to use firefox. Am I the only one experiencing this? Did somebody try to look into this ? At a glance I see no great difference between the css settings of the two skins that could make this effect happen, but I'll look further into it.
