Programs have interruptions in UI responsiveness

[Karl-Philipp Richter]

All programs started from within cinnamon have interruptions in UI responsiveness which last from less than a second, i.e. hardly noticable, to more than 5 seconds, i.e. making the UI "hang". The phases where user input is possible and the UI updated are in the same range of duration. The interruptions occur constantly and start a few minutes after the desktop has started, so that the system is consequently hardly usable.

The system resources monitor shows that 1 core of the CPU is used constantly with 100% by `cinnamon`.

This seems to be fixed in 3.4.0-1~zesty0 of PPA ppa:embrosyn/cinnamon.
