Can anyone please tell me how reduce (scale) the aperture size, keeping it even like the -effect overlays?
I'm currently trying to change the 'shadow_mask_usize' and 'shadow_mask_vsize' parameters but with mixed results.
For example I'm having problems with the aperture displaying more red in some horizontal bands. The following is a pure yellow screen with the aperture displayed on top:

Any ideas what might cause this? It gets worse depending on the uv scaling.
