Description Christian D. 2006-02-18 12:06:07 UTC 
Version:           3.5.1 (using KDE 3.5.1, Kubuntu Package 4:3.5.1-0ubuntu7 dapper)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-15-686

Sometimes while surfing the web, the client area (or Web site view) becomes suddenly black (solid black block). If you scroll up and down you see parts of the (correctly rendered) web page in some random locations. Sadly, this is not really reproduceable. I hardly suspect this to be a memory bug of some kind. If you select part of the web-site text, the text becomes visible again but the background of the text stays black. Switching tabs does sometimes help but does not completely restore the correct behavior. I have this since approx. KDE 3.2 or maybe 3.1. It has been reduced since then and does not happen as often as before. Now it happens approx. once in two weeks, were with KDE 3.2 it happened nearly every day. I'll try to get some screen shots when it happens again, and will append them to this report.

I'm using the nvidia-legacy driver from ubuntu restricted. With the open source drivers it didn't happen to me at all.

I can confirm the presence of this bug, introduced with KDE 3.5.1
With previous versions I had never experienced the problem.

The bug is impossible to reproduce since as Christian said it happens randomly, but quite often. Refreshing the page won't help, only opening a new tab or window solves the problem.

Sorry for the repost, I forgot to say I'm using KDE 3.5.1, QT 3.3.3, xorg 6.8.1, kernel 2.6.15.3, all compiled from source with GCC 3.4.2 / glibc 2.3.4
The problem happens with both radeon driver from x.org and fglrx binary drivers from ATI.
