It's a 'feature' of VLC and the hardware H.265 decoder on some signals. The colour plane slips down by a few pixels. It's been like that for years.

Similarly, the beacon can be decoded only on window 1, using a software decoder and not on the other windows which use the hardware H.264 decoder.

Brian,

Thanks for the reply, it’s only I have never seen it on the pc viewer, so must be a pi 4 encoder feature.
