System Information
Operating system: Mac OS Catalina (version 10,15,7)
Graphics card: Radeon Pro 555 2GB / Intel GD Graphics 630 1536 MB

Blender Version
Broken: Version 2.93.0 (2.93.0 2021-06-02)
Worked: Version 2.91.0 (2.91.0 2020-11-25)

Short description of error
Normals are glitching when I export and then import a .FBX file with an embedded texture on Blender 2.93.0

Fact : When I export a .FBX file from Blender 2.93 and import it in Blender 2.91.0, it works well.

Exact steps for others to reproduce the error

  1. Export the mesh as an FBX with the embedded texture

  2. Import the FBX and see the normals glitching. You can see that the imported .FBX has created a normal map node and another image texture on the alpha.

Here are my settings for the FBX export and import

Here are the files if you want to try :
donut.fbx

donut.blend

Thanks a lot in advance for your help !

Merging this to blender/blender#89630. This is not related to normals, but a limitation of alpha blending. As a workaround, you can disable Show Backfaces for now.
