Try disabling dithering completely as a test. Then you'll see what kind of movement I mean.

My tests show that the smallramp.ytp test is the best to detect these "movements" (noise). They become obvious near the dark end of the ramp. It is also useful to detect banding, so it is easier to set the balance between dithering and potential banding.
It seems the old TN panel in my PC monitor isn't so bad after all, since noise is clearly visible as soon as I switch to 7-bit.
