Do you mean that the monitor is switched off? Or do you mean the secondary display window disappears from that monitor? There is an existing report that the secondary display window disappears briefly if you switch between the Develop module and any other module. I experience this myself too, but it is only for a few seconds (irritating enough), not permanently.

No, the screen itself continues to work, but the window with the live loop starts flickering or disappears. Then I have to switch it off and again on and it repeats in a while.

[JohanElzenga]

Yes, that is the same bug.
