Thank you for the reply. Indeed removing the dock worked.
More precisely, I noticed that I had (accidentally) connected two mouses one
via the dock and one wireless via a usb port (and the trackpad ofcourse).
Taking one of the two mouses out of the equation solved the problem for me. No
more crashes since.

Title:
Screen freeze
Status in mutter package in Ubuntu:
Incomplete
Bug description:
When having more than one window open, e.g. Firefox and a terminal and
then to swap between the two. The clicking with the mouse stops
working but it still moves. For instance when I hover over text or not
the cursor does not change. Sometimes I can still click or select text
in the original window but the coordinates of the mouse are not where
the cursor is displayed. Sometimes the keyboard dies too e.g. Alt+F2
does not work. Killing XOrg (if possible) seems to revert things to a
working state.
