Broken: 2.82, 2.83 ff1040c6fefc
Worked: (newest version of Blender that worked as expected)
Short description of error
When in the viewport I want to switch to Material Preview, the object get pink and I get in the console this error
GPUShader: error: too many samplers in shader.
This happen when I add/link too much mixshader or mixrgb node
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
As this is specific to this file, I attach the file
If you remove one mixshader or one mixrgb it's ok, the preview is fine
