Discolored live stream

I noticed that after the upgrade to 1.34.22 when I click to zoom a live stream the video sometimes "loses" a color, like a VGA monitor with a bad pin. Changing the zoom sometimes changes the lost color or restores to correct color. This occurs even when the camera is in B/W mode (still a color stream?) and will always happen if I keep zooming in.
This occurs on all cameras and only in live stream.
I cannot say it was the upgrade as I do not zoom often, but I did not see this before.
I am not sure where to start looking so I have made no changes yet.
ZM 1.34.22

I changed the color depth from 32bit to 24bit. The B/W streams seem fine. The color streams, not so much. It now substitutes colors.
I also removed the setting for DecoderHWAccelName with no change in behavior.
Any thoughts?
Thank you,

Only when zoomed? Sounds like we are using the incorrect colour space when generating the zoomed image.
I will have to try to replicate it I guess.
Edit: Easily replicated. Will fix soon.

Thank you for taking a look at it. The house looks better with red trim.
