I have an AMD 7900X and an RX 6900 XT. I was getting this exact thing in 3.1.11 on any model at 1920 by 1080 PNG output. Usually it would start like that, and proceed to fill the entire movie with blackness eventually.

It will still do it if I process two videos at a time. Glad to hear I’m not the only one with this issue.

Thank you for your reply.
Of about 8 enhanced videos I did so far, this was the first one with the defect. The black box appeared in the last 25% of the encoded video. I never do more than 1 job at a time.
Here is screenshots frame by frame for illustration:

Hello and thank you for sharing the images of this issue,

Our dev team has been made aware of this bug and we are working to reproduce the issue and find a solution.

Thank you.

that is quite an old issue that appeared first a year ago or so also on nvidia cards (rtx 2070 super).
