Resolution Note (fix version 2023.1):
Fixed in 2023.1.0a13
Reworked the video module's player loop integration so it behaves more similarly in editor to how it does in builds. Also now triggering a texture update in PostLateUpdate if a call to VideoPlayer.Play/Pause/StepForward that causes a new frame to become available was made during the iteration. This way instant-start can be achieved rather than having to wait one frame.
