Short description of error
Error in map textures in linked objects from another blender file, this issue is not present in the 2.8 (blender-2.80.0-git.cc600de6695a-windows64), the textures appear like these were at beginning in the original file before they were modified.
Exact steps for others to reproduce the error
open a new file then link the objects from library, if these objects have textures modified it will appear now such they were at beginning i the original file
Based on the default startup or an attached .blend file (as simple as possible).
