System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd7
Worked: (optional)

Short description of error
when adding texture sets (diffuse, normal, roughness), after the 7th set it seems that EEVEE cannot handle it and change to pink texture in render view.

Exact steps for others to reproduce the error
add a new node texture to a mesh,
create a principled shader with texture sets with images in the normal, roughness and color input,
combine the shader with another similar shader with texture sets using the mix shader.
repeat this process until the 8th time, texture will turn pink in eevee render mode.

Can confirm, getting this then

GPUShader: linking error:

@fclem: I assume there is not much we can do here? So I guess this is a Known Limitation (and could be closed?)
Confirming for now though...

Yes it's a limitation. This is imposed by the GPU there is no real workaround this. Note that even high end gpus are likelly to have the same limits.
