  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. 
Yes, this is a known issue, annoying a lot of people, including some of
the devs (those that aren't using Macs), see
http://jira.xwiki.org/jira/browse/XSTOUCAN-9 for more details (the
comments are full of information and tips).
