Some regular noise

[iqch]

Before denoise pass image looks strange

[carsonbrownlee]

bizarre, @johguenther perhaps a RNG related tiling artifact on windows?

[johguenther]

@carsonbrownlee can you reproduce this with e.g. usdview? I tried ospExamples.exe from the v2.7 packages and don't see regular noise in PT.

[carsonbrownlee]

@johguenther no I am unable to reproduce using v2.7 on ubuntu 20.04 on either usdview or houdini.

I've built right now ospray2.7 over Houdini18.5.672 tbb - and built hydra delegate over this ospray - I see same regular noise - in usdview oro in Solaris stage view. Win10/MSVS2019

Is this noise pattern specific to one scene or present with all scenes / lights?

[iqch]

This scene contains just polygonized utah teapot. It is visible at any hydra-driven viewport and hides after denoise

Even denoise does not eliminate this artifact

[carsonbrownlee]

@johguenther could this issue be windows specific somehow?
