widget (not only) dithering problem?

Hi, I have a widget and there is a weird dithering effect when I zoom out, it also appears not only with my widget, but for example with my hero outline, here is a video

Is there any way to fix this?

It seems like it has to do with Anti-alising. TSR looks somewhat good but it has other problems, all others have the same problem with dithering, I use TAA for now, how is this handled in other games?
