dunno if theres a post on this already, couldnt find one, but i remember reading about it earlier.
in an interior rendering im doing right now, there is a glowing line across the middle, i think where the horizon should be outside. its subtle but very noticable. any solutions?
i will post as soon as i get my host shit figured out.

Can someone do me a favour and find a real simple test case scene for this bug? less objects the better, and then email it to me at

Here's a test I did with indigo 6t5, not only do I get a horizon artifact but a vertical one.
NOTE: I gave it some burn to make it more noticable.
Will send this to you Ono, hope it helps

I have joegiampaoli's test scene.
But if you have another test scene, that would be good thx.
The simpler the better as well

Hmm.. this bug only seems to occur with physical sky. Can anyone give a counterexample?

Your statement seems right, ive never seen it when there is no sun. I discovered the bright vertical line too but joegiampaoli was faster than me

My scene is quite complicated, ill try to simplify it and see if it still does it. If it does ill give it to you.
