Hmmm, that scene is heavy on the export, dunno why. But that really doesn't matter.

Just by looking at your two renders, I can tell that the one has much more samples then the other, focusing on the caustics on the bottom left side. You can see it gets a lot clearer, and there is a lot more energy in the caustics on the second(bottom) render. But I think I know what you mean. It's like in one rendering cycle there is that one random area that just keeps getting more samples, while other remains undersampled. In other cycle, on the same frame/scene, that undersampled area switches, and you are left with two different results, where on render we have some caustics, where on the other one those are gone, but we have them present in other place. Maybe playing with MLT settings could be the reason, like MNCR?

" I can tell that the one has much more samples then the other"
Both pictures took the same amount of time to render

In general I can say that with Indigo 3.8 everything was good, but starting from version 4 it became bad

Unfortunately, since version 4 MLT mode is not completely suitable for animation, and for static pictures its use is now questionable. And the most frustrating thing is that in all my tests Indigo before version 4 gave the most beautiful and correct caustics from my point of view

Hi.

I'm having some problems with hdris. I don't know why, but sometimes when i rotate them i get a strange light effect, it's as if a high-quality hdri becomes a very low-quality one, it also the background image changes its colours.

try after rotating hdri toggle render mode [ path tracing ] to [ bidir mtl ] and back to [ path tracing ]

in some situations, this shamanic ritual helps

That "shamanic ritual" its not working for me, it used to work in earlier versions of indigo but not this time. That is why i mention the problem, is very annoying to re-export the whole file to solve the problem.
