First image - I have these rendering-parameters:
1920x1080 (60p for video),
sharp activated
Motion blur deactivated
antialias 196x
DOF = 25x

------------
Second image - I have these rendering-parameters:
1920x1080 (60p for video),
sharp activated
Motion blur activated
antialias 196x
DOF = deactivated

------------
Third image - I have these rendering-parameters:
1920x1080 (60p for video),
sharp activated
Motion blur activated
antialias 196x
DOF = 25x

----------
Now, analysis.
In 1 and 2, you can see the car in the full sharpness, because only one (of two) parameter is activated.
1 screenshot - activated DOF
2 screenshot - activated Motion Blur
3 screenshot - activated DOF + Motion blur = glitches
My GPU is AMD Radeon HD7850 2gb

And same problem also with screenshots.
------
IF I will change antialias from 196x to 100x - look below \/ \/

with 100x - exposure and dof goes wrong
every parameters (like Depth of Field) are configured correctly
