Sorry for the late reply. If you happen to read this it’s an NVIDIA Geforce 1660 Super. I had the same problem with my last graphics card which was NVIDIA as well. I am running the latest driver.
I am using a 55" Samsung 4k TV. I’m using 3840 x 2160 display resolution. I’m at 200% scaling to see better. I’ve messed with different scaling, resolution and font size settings to no avail. I’m guessing this is something that will never be resolved as it’s such a small issue. It annoys me though as I have to guess what type of audio channel I’m creating!
I have no other issues with any other software, which is graphics and video-based!
