Have noticed that a horizontal green line pops up from time to time at a random location when using the Legacy AV card with my OSSC pro.

This happens with both S-Vidéo and composite sources. Have the latest version of the firmware.

I bought the extension card 2 months ago. It is in an 3d printed enclosure directly plugged to the OSSC. I am using the OSSC standard PSU and I have tried with a 5V 4Amp with same issue.

Happens at 6x and passthrough in ALM , have not tried other modes.

Any idea?
