See: Camera Rotation stops when mouse hits wall of Game Window - Programming & Scripting - Unreal Engine Forums
I’m not sure if this is intended behavior but APlayerController | Unreal Engine Documentation does not say that we should not set this variable in the BeginPlay() so therefore I assume that it is a bug.
bShowMouseCursor = true;
and putting it somewhere else (like toggling it with a key) fixes the problem. But putting it in BeginPlay() bugs it again.
