Aspect Ratio Problem

[miruket]

I have this problem that appeared like 3 months ago and never said anything thinking it would fix. But after awhile I just launched bo2 again and it continues. I used to play on 800x600 it looked like 16:9 but now it didn't, I don't know how to describe it so it looks like the attached image and it didn't look like that before. Any fix?

NOTE: this only happens in bo2.

It used to look like this:

(I changed the resolution to show how it basically used to look like at 800x600)

EDIT: To fix this issue you need to set the aspect ratio to "wide 16:9" in both plutonium_mp.cfg and plutonium_zm.cfg.

The line should look like the below:
seta r_aspectRatio "wide 16:9"
