I get a similar issue, my video card is an ATI and I use the radeon drivers.

Same symptom as you - plasma stops updating it's widgets like clocks and
stops responding to the mouse. Keyboard works.

In my case, it's usually linked to nfs and smb mounts that went away
(eg, if I forget to umount my NFS media server at home and go to work)
which indicates a blocking issue somehow. I've read many reports on the
internet that krunner is somehow involved, so that might be a good
starting point for investigation. krunner is the thing you get in KDE
when typing Alt-F2
