Hello,
I have an issue with DeckLink Quad HDMI Recorder card. The captured video is shifted by approx. 200 pixels to the right and the rest of the shifted image appears on the left. I have attached an image of the issue. In the picture there is a grid of all four inputs from the Quad HDMI Recorder.

I am running on Ubuntu 18.04 with kernel 5.4 and the same result is produced when using ffmpeg and CasparCG. Firstly I installed Desktop Video 11.7 and discovered this issue. Then I tried installing Desktop Video 11.6 and it seemed it solved the problem. I let it run over the night but when I checked it in the morning the image is broken again. I have tried different signal sources and different processing software but it didn't help so it seems like the issue is caused by the Decklink card. How can this be solved? I really need to get this working.
Thank you
