I found a possible cause for this. Testing a fix now. I believe it is related to auto_brightness_contrast, which changes a value whenever it triggers and that value is not being reset between images, so over the course of a batch it might be getting more and more out of whack. While I’m testing, you could try turning this off and see if the issue goes away? Alternatively, you could set perlin_init to true, because that does cause this variable to get reset between images.

Not that I’m aware of. I’ll do some tests. Would be helpful if you could post your settings.
