Comment 5 for bug 784523

@"If I don't stop the 'flashing' immediatly, but e.g. after 15 minutes, a running application (Thunderbird) does not answer anymore and has to be terminated."
After some minutes, applications are alive again.

@"I am running Natty on a Netbook with an additional screen -- the 'flashing' occurs only on the display of the netbook, not on the additional screen. And it occurs almost only when I pause and the system is idle."
1. It occurs also on the netbook display, when I'm using it without additional screen.
2. It occurs, when _the user_ (me) is idle, not when _the system_ is idle.
