Occasional Sudden Blur with Post FX At Certain Settings

[Gaiba]

With Post FX set to Ultra (and maybe Very High and High) I'm getting this weird sudden blur on occasion that affects practically everything on screen. It'll just pop in and out all of a sudden. I don't know if it happens on Very High and High, but I know I never see it with Post FX set to Normal.

Here's a before and after, you can notice it best by looking at the ground and the billboard toward the right:
Normal: https://steamuserimages-a.akamaihd.net/ugc/786357435034899522/F2697CC98A744793FF269B6E82FE4989E1A8E7FC/
Blurred: https://steamuserimages-a.akamaihd.net/ugc/786357435034899853/73A95A35D866893AB9880F07393FE343AEF55905/

This isn't just motion blur or anything because it pops in and out randomly, so I'm not sure what's up. I know I can turn Post FX down, but I'd like to have it on, so does anyone know what the deal is or how to address it? Thanks.

Hm from what i found out...
Post FX
Bloom lighting, motion blur (optional), glare, lens flare, persistent background depth of field, and high dynamic range (HDR) lighting are the main features of the Post FX setting, though on occasion you'll also see crepuscular rays (God Rays), heat haze, and a few other volumetric effects. Note, Ultra or Very High is required for In-Game Depth of Field Effects, and Motion Blur.

So on v Hight and Ultra it adds Motion Blur. I know theres a option in game to tunr the strenght of motion blur down but i dunno if it turns off by that. Maybe theres still a little of blur left.
