If player is beyond the level,instead of the usual HOM effect GZDoom displays black screen
GZDoom 2.1.1 and lower


GZDoom 2.2.0 - GZDoom 2.3pre

So? Why should there be sky? Is there any legal piece of sky visible in the lowermost shot? I don't think so.
This squarely falls under 'Undefined behavior' Sky gets drawn when the engine thinks it needs to and in that shot it doesn't.
