Description Prasad 2011-01-03 08:58:35 PST 
When using overflow:hidden in our css, we have a huge performance impact in rendering/scrolling.
We try to avoid overflow:hidden as much as we can but for some things its unavoidable.

The user experience goes towards zero, as a list with items and this css attribute is very sticky and hard to handle.

Please follow http://trac.webkit.org/wiki/QtWebKitBugs when reporing bug here.

I close this as invalid because I suspect your problem is in the graphic system you are using. I suspect the problem actually comes from the clipping created by the "Overflow: hidden".

Please include a profile to reopen this bug.
