System Information
Operating system: Windows 11 Pro N - Version 10.0.22000 - Build 22000
Graphics card: MSI Nvidia RTX 2070 Super

Blender Version
Broken: The latest 3.1.0 Alpha, and the latest Stable 3.0
Worked: Last I tested that worked was the Stable 2.93

Short description of error
When I bake a texture with GPU + Adaptive sampling that directly uses Vectors as Colors, the bakes are incomplete, or buggy.
When I dont use texture coordinate, and I just use the material color, it bakes fine.

Exact steps for others to reproduce the error

Open .blend file
Set device to GPU
Select Noise Threshold
Bake image textures of selected objects

Sometimes it seems to bake specific faces of the model perfectly. Sometimes theyll be darkened, sometimes weird lines and missing pixels will appear

Hi, thanks for the report. I am unable to see any differences between 2.93 and 3.1.0

2.93.0	3.1.0

Perhaps an issue for specific GPUs only? (or I am missing something to reproduce)

Then what can I do? I have no other options.. Ive updated drivers, Ive deleted caches and reinstalled blender, and another user experienced the same problem on their system using my file. No one I ask has any clue what to do...

I really need to be able to bake... its just so irritating..

I'm able to reproduce this issue on both Blender 3.0 and 3.1. The issue might be specific to Nvidia GPUs.

Unchecking 'Noise Threshold' in the render settings seems to fix the issue.

@deadpin was able to reproduce this issue with GPU+Adaptive sampling so I will set its status to Confirmed

(Feel free to change the status. I personally can not reproduce)

I suspect this is related. Baking textures (Combined) from a multi material object only the first material in the list bakes right. The next materials bakes a mix of the previous materials + their own. This happens in Blender 3.0 with GPU and Denoise/Noise Threshold on. If I turn off Denoise and Noise Threshold the textures will bake right, albeit a lot slower and more noisy of course (If i switch to Diffuse though - the issue is back with these settings too). Whether I use OptiX or OpenImageDenoise seems to make no difference. Switching the materials in the list it will still be the top material that works and the ones lover in the list will be messed up. If I bake in CPU I have no issue.
