Public bug reported:
When using Firefox the system first hangs from time to time. Usually this
happens while scrolling.
After a while the system does not just hang, but the whole system freezes
completely; so that a hard reboot is needed.
May be related to Bug #1162073
Another side effect I observed is that certain letters (e.g. 'I') are
displayed in a strange way (firefox).
