Short description of error
When sculpting an object with multiresolution modifier, If viewport shading is changed to material or render, any image texture in the object's material goes black or invisible in cycles render. everything works fine in object mode.
Upon more inspection, the UV of the object with multires modifier is completely black when in sculpt mode and normal otherwise

Exact steps for others to reproduce the error

1. Add a cube
2. switch 3D viewport shading to material or render
3. create a new material
4. add any image texture to the material and connect it to the base colour of principled BSDF
5. go to sculpt mode
6. add a multiresolution modifier on the cube and subdivide (ctrl + 2)
7. and the texture does not show (or cube object is invisible in cycles)
