Problem with aspect ratio

[TailsXHeeroes]

So, after I enabled full screen mode in setting.ini, for some reason the screen ratio started to work strangely. But, when I use window mode the aspect ratio works fine.
I tried to change something in ScreenWight and it worked, but since I use a 16:10 monitor, and I... don't really like 16:10 aspect ratio, more than 16:9.
Is there a way to fix this?

Seemingly, when I set a 570 Screen Width (for a 3440x1440 display), it causes the game to crunch to the side of the screen when running with fullscreen mode (and hardware rendering). This issue seemingly doesn't occur with the software renderer.

Luckily the software renderer in fullscreen doesn't have that issue and let's me use AFMF for frame interpolation.
