Why does the level of blurr keep changing?

This hasn't happened before today. I don't know what happened, but on rocket league something keeps flipping on and off, it changes the color and blur (I think), its hard to tell what it is. I've tried messing around with the global presets but that hasn't worked, and the one thing that sort of fixes it is going to d311 and clicking on "Copy depth buffer before clear operations", though with that enabled it only flips on and off more quickly and less frequently, like mini flashes.Heres a video of whats happening:

Depth buffer doesn't work with online games by design. Disable the DOF shader and you won't have that problem.
