Hi good morning moderators... and tech support?

so im having this problem where the screen is of two shades when I run a map but it isnt so when Im in the command bridge. 

This started when i changed my system resolution to 1024x768. now i have vertical bands on the screens side, but the gameplay experience (OMG the SMoothness).

So i would very much like to play like this at system resolution of 1024x768, please note that this problem wasnt there, but when i was running the game at 720p system resolution the smoothness would fluctuate and wouldnt look as smooth (supper choppy corpse explosion) even if i reduced in game resolution to 640x480.

also its more apparent when you move about the map. this line doesnt appear in the command bridge.

Can you all please fix this. My system specs are as follows

Ryzen 2500u

16gb RAM 2400mhz

Vega 8 graphics :(

1 TB SDD

Acer aspire A315 41
