Having been working fine with MEP 2020 for months, a few days ago, my Program Monitor window started showing a double image, two identical side by side, on the video stream of the project I am working on. See pic attached.
I have loaded old projects and started new projects and the problem persists so it implies there is something set wrong at the heart of the program.
If I use titles or section effects, the dotted line box appears in the correct aspect but with the double image underneath, so it makes viewing what I am doing impossible.
When I render/export the videos, the resulting video appears normal, without a double image so it is entirely related to the program monitor window, not to any effect being applied to the videos in the project.
Anyone any idea what is happening here and how to stop it, please?
