System Information
Operating system: Linux-5.14.0-3-amd64-x86_64-with-glibc2.32 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 495.29.05
Blender Version
Affected driver versions:
495.29.05495.44Worked: With GPU drivers prior to
495.29.05.Worked: Oddly enough testing with Blender from prior to the Cycles-X merge with driver version
495.29.05does NOT have this issue.Short description of error:
As per request of Patrick Mours at Nvidia I have created a task here. https://blender.chat/channel/render-cycles-module?msg=cJvvBJbttccHwtvG8
When using OptiX denoising with one of the affected GPU drivers listed above on Linux with recent versions of Blender 3.0 there are artifacts. Using an older GPU driver like
470.63.01or a version of Blender from prior to the Cycles-X merge seems to resolve this issue. Here is an example of OptiX denoising in the viewport of the default scene with the artifacts:The artifact can change a bit based on what's on screen and how the scene was rendered. For example, changing the scene to be rendered with the CPU but denoised with OptiX shows this result instead:
Exact steps for others to reproduce the error:

Adding the Linux platform as this issue may be limited to it. I'm also assigning it to @pmoursnv as per his request in blender.chat.

Changed status from 'Needs Triage' to: 'Needs Developer To Reproduce'
Since this is already assigned, will change status to reflect that.

Can confirm the issue, worked fine with 470 but strange as you say with 495.

Not sure if we need to fix this on our side or if it can only be done in the driver, but marking as high priority until we know which it is.

This is not just limited to linux, I am experiencing the same on windows
Current system - windows 11
Card - Rtx 2070 super, Driver version - 496.49(gaming drivers)
Blender version - 3.0 and up
Also, not just viewport, it affects the render as well
