visiting the site http://www.klidnemesto.cz causes 60-99% of one of the cores of my 2GHz C2D to be used by the X process and firefox.

This is not happening when the firefox window is minimized.
This is not happening with the Konqueror 4.4.3 browser

For me, the CPU usage on a 1.6ghz asus eee pc 1000h is around 20%, so not so much. X constantly stays at 10% (not influenced by the URL above). When I scroll the page though with the mouse wheel, the scrolling DOES feel noticeably more laggy than on other pages/tabs. So at least it does have a slightly noticeable, although not devastating impact on performance here.

hajma, can you still reproduce when using a current version?

the site has changed, so I cannot reproduce it now.
I think it's safe to close.
