Tearing/Artifacts in KDE 4.2 in Firefox

[chalewa]

Anyone notice any artifacts while using Firefox in KDE 4.2?
For some reason when I open new tabs in firefox, I get this weird artifact border at the bottom of the tab.

Anyone notice anything like this?

Yes, I have the same issue. In fact I'm gonna post a pic of it to get an exact example. I'll let you know if I find a fix.

Check this method (http://ubuntuforums.org/showpost.php?p=6798867&postcount=2). I found it in this forum but I don't remember the thread...
It works for me.
