Kubuntu hangs/freezes during Hangout call

[Volkan Gezer]

Hello,

KDE works fine in daily usage, but after making call using Google
Hangout for 1 hour or so, it starts freezing for some seconds. The
only thing I can do is using the mouse, everything freezes (sound,
hangout, chromium, panel etc.).

I tried to change scheduling settings, but it did not help. Also
pressing other keys to switch into other TTYs don't work.

What else can I do?

I am using Kubuntu 13.10 x64 with KDE 4.11.3

Thanks,

Best regards,
