This is probably related to bug 176014. Thanks plasma with the raster paint engine seems way more crashy, so probably is an upstream issue, we should come up with some simple test case to be really sure tough Bug 194309 looks similar to this but in KRunner. I have just installed KDE 4.3 beta 2 (from Kubuntu 9.04 packages) and the bug is still there.

Now it is inside the WebKit code when showing a web page, so that is definitelly something more related to Qt than to KDE code itself. Thanks *** This bug has been marked as a duplicate of bug 176014 *** |
