Hi,
I just bought a B&O Beovision 1 CRT and have hooked it up to a Mister FPGA device for retro gaming over scart and I immediately noticed a very intense flickering (especially in the corners) when I enable 60 Hz modes in the various cores. Very prominent in SNES games as an example. 50 hz PAL mode works perfectly fine with no flickering. Is there a setting I can tweak in the TV to solve this?
Here's a video of the issue: https://youtu.be/jL6xkKcuvEo
