After upgrade from Kubuntu 11.04 to 11.10 the bottom panel started to freeze every now and then. It stops working for about 1 or 2 minutes. During this time I can't switch windows (but ALT+TAB works), can't switch workspaces (but CTRL+F1 - F4 works), I'm unable to start the launcher (but ALT+F2 works) or the calendar or anything else. The whole bottom panel is out of order for some time. After a while it works again and I can see that all previous clicks are quickly processed.
The problem repeats several times a day but I haven't found any regularity or a reason why it happens.
I upgraded KDE to 4.7.3 from ppa:kubuntu-ppa/ppa, but it didn't help.

Same situation on 3 laptops i use KUBUNTU 11.10 on all:
dell inspiron 1520 nvidia card
dell inspiron q17r intel (optimus-nvidia) card
hp g72 intel (switcheroo ati) card
Happens only when desktop effects are ON.
So i dont think that problem is connected to video card,
