System Information
Operating system: macOS-12.5.1-arm64-arm-64bit 64 Bits
Graphics card: Apple M1 Max Apple 4.1 Metal - 76.3

Blender Version
Broken: version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560
Worked: (newest version of Blender that worked as expected)

Short description of error
I mixed 2 Principled Shader and created an image texture node as a mask connected to the socket FAC of the Mix Shader Node. I'm not able to see the result in real time in Shading Viewport/ Render and Shading Viewport/Material Preview only in Shading Viewport/Solid

Exact steps for others to reproduce the error
Steps

Start Blender

Simple cube
Added first Principled BSDF Shader and connected with Node Wrangler - Maps: Color, Roughness and Normal (A)
Added second Principled BSDF Shader and connected with Node Wrangler - Maps: Color, Roughness and Normal (B)
Mixed these 2 Principled with mix shader (C)
Created a texture - image texture - New - 2048x2048px put the color socket in the FAC of mix Shader node (C)
Switched from Object Mode to Texture Paint, tried to paint but in Viewport Shading/Rendered and in Viewport Shading/Material Preview changes were not updated and not visible
If I go to Viewport Shading/Solid I see where I painted and when I switch to Viewport/Render I see the mask applied correctly
The issue is I do not see the instantly masks when I paint but I have to switch from Shading/Rendered to Shading/Solid and then again to Shading/Rendered to see the mask applied correctly

To see the result of the mask I must switch to Viewport Shading/ Solid and get back to Viewport Shading Render

Thanks

I can't seem to replicate this issue using the following setup. Should I have done something differently?

If you go in Viewport Shading/Render and try to paint you won't b able to see the final result in real time, I mean it seems that nothing happens in Viewport Shading/Render. But if you switch in Viewport Shading/Solid and get back to Viewport Shading/Render you'll see the updated paint. Hope this is clear :)

Thanks. I tried that, but it seems to work correctly in my case. Can you attach your file in case my file is different somehow?

Ah, I see you are using Cycles. This is a known limitation in Cycles. See #86787.
