Description gmud 2008-09-23 15:03:06 UTC 
Version:           4.1.1 (KDE 4.1.1) (using 4.1.1 (KDE 4.1.1), Kubuntu packages)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-19-rt

Some webpages with fixed background-images make konqueror scroll slow, e.g.
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=360090198960

I could not make a testcase of this behaviour yet since its complexity... It seems that the fixed background has something to do with the lack of perfomance. I created a normal webpage where I have a fixed background with some images in some divs, these work very well. So, I assume it must be a combination of some Javascript/fixed background/stylesheet problem...

This is due to two scrollbars... There is a patch in qt-copy + fix in latest khtml that should address it.
