Kubuntu Hangs intermittently. Video goes crazy from time to time.

[Michael Krueger]

For me the same. After the latest update to KDE 4.3.2 on jaunty it seems that
e.g. dolphin is extremly effected, by intermitted hang's. This is really annoying...
It feels like an incredible slowdown. The systemtray also had problems again
this morning rendering all the icons. Only after clicking into the tray they
showed all up.
