Hi !
I'm opening a new thread as my previous one was actually solved and was getting confusing
So, I'm using the Indivision MK3 AGA on a recently repaired A1200. The issue I'm mentioning even occurs when everything is removed from the 1200, with several (old & new) PSUs, several HDMI cables... I'm really happy with the great picture quality & features
Horizontal lines appear quickly after booting. Potentially anywhere (even the workbench), when the Indi is set to a high mode / pixel clock, like my 1920x1080. When lowering it, it doesn't happen anymore at all (like 1280x1024).

I'm showing how I insta-trigger the issue in the SkillGrid game.
But it can also appear on the WB as seen here : https://www.youtube.com/watch?v=28rH2OWak80
What is interesting is that the bug follows the screen I'm dragging.
Thanks a lot
