Square artefacts (again)

What’s the workaround to fix the dreaded square artefacts again? Adaptive Dome is now hardwired into the dome light and can’t be switched off, right?

Oh no, the monster rears its ugly head!

Could you send the scene so we can take a look?

Not able to send that one unfortunately. But it’s a pretty well known problem, right? Been around for a few versions already…

Yes, the issue is known, but it has different triggers. We’ve fixed most of them, but alas some remain.

Yes, I did find the adaptive dome switch and turning it off fixes the problem. I guess I’ll go with that though it makes calculating the GPU cache super slow, for some reason.
