Research direction
Start by reproducing the issue with OBS Studio 30.2.3 on Windows 11 using the VLC / Media source and a transparent video layered over another media source. Inspect the VLC source handling and verify whether the alpha channel is preserved; done means the transparent background renders transparently rather than opaque.
