Game becomes blurry when reloading Peacekeeper

Evidence: See attached video

When reloading the peacekeeper, the game becomes briefly blurry multiple times during the reload animation (and it lingers for a short duration after). I tested every other weapon in the game and this doesn't occur for any others, and it is not a skin dependant issue either as I changed my skin multiple times to check.

I tested to see if it was related to a graphics setting by enabling one setting, checking to see how it impacted the blur, and then disabling it. It seems to be caused by disabling TSAA. I also checked to see how it was impacted by FOV, and the first couple blurry pulses are barely visible at the edge of my screen, but the final pulse impacts the entire screen which you can see clearly by looking at the blue lines on the ground and at the edges of walls. It also mainly seems to affect the right side of the screen, if you look at the left blue lines they dont blur anywhere near as much as the right side does. 

I checked whether it was related to resolution / aspect ratio too (I play on 2304x1440 so 16:10 stretched res), as I switched to my default 2560x1440 16:9 res and there was no change.

I also asked my friend to test this too to make sure it wasn't specific to my game / system and they confirmed this was present for them as well.
