I can confirm this with further testing : If no KDE program try to access the web, no problem. But if one tries, then problem comes one by one depending on the program(s) started.
I've been told I should report that to KDE maybe, can I get a word from you to do so or not ? Thanks -- High cpu load with newest KDE https://launchpad.net/bugs/66232 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
