I believe this is a bug in ubuntu and not in Krusader, smplayer or Skype. Did some research online and issuing sudo killall -9 unity- settings-daemon seems to have an effect on things - although it does not solve the glitches.
** Description changed: After booting, everything works fine for a while. But after a while, the GUI of various apps stop working and start being misaligned and badly rendered.
