When the camera height slider is lower than the green "block vanish height" slider some objects that would normally float up and disappear will be partially rendered. These partially rendered objects appear to be rendered in the same way as the cutouts formed by moving close to an object close to the height of the player camera (as set by the white slider.)
I should note that the graphics card in this system is rather outdated at this point (GTX 460m) and may just be unable to perform some form of shader mixing that already exists in the game code. In fact, my GPU only supports DX10 shader model 1.0, below the recommended minimum. In case it is relevant, I've included the Display Devices output of dxdiag on my device here. This one may be a wontfix if it doesn't occur on more recent hardware.
