Hi,
sorry for the late reply. The desktop behavior is controlled by the kdesktop process.
When your desktop stops updating, from CLI type:
ps aux | grep desktop
and see if there is something like:
username      8414  0.4  0.7 260192 28956 pts/8    Sl   12:50   0:00 kdesktop

If not, kdesktop has crashed. You can type:
kdesktop & from CLI to restart it (or alternatively Alt-F2 and then kdesktop).

If this brings everything back in order, please let us know because we need some more advanced testing to understand
why and where kdesktop crashed.

Cheers
  Michele
