Sometimes, sometimes not. Sometimes the noisy screen is busy (e.g.
updated), sometimes even normal redraws happen (so the noisy screen is
overwritten with the correct content), and sometimes everything stops,
including screen updates.
The triggering of the bug seems to be strongly GSM-related. AFAIK, it only
happened when I login into the GSM network, place a phonecall or receive a
phonecall or short message. Thus, when I have no GSM traffic for some
hours or even days, the system seems to remain stable.
