Bands of noise in render when using "custom texture" DOF

[Paul-Simon]

This seems to have been the case for a long time, and should apply to all versions of Corona, even the latest ones with the improved DoF features.

Image-based DOF (1024 samples):

Circle DOF (1024 samples):

These bands of noise in the first image are really tough to deal with, and seem to never go away no matter how long you render.
The even noise in the second image is of course something to be expected, and is no problem to deal with.

Even when pushed to enormous amounts of samples, the bands stay clearly visible:

Did you try to change enviro sampler and/or random sampler in dev/debug settings?

Changing the enviro sampler appears to work. Thanks!
However, I assume it would be nice to get this to work in the default “new improved” sampler too.

I think it’s already fixed in daily builds and definitely should be fixed in Corona 2.

Still present in Daily Builds at the moment - as noted, only with a Custom Bokeh map, and only with the “New Improved” random sampler (changing that to Stratified made the lines go away)

Just an update - we’ve managed to reproduce this in some test scenes, and we will do our bets to fix this asap.
