Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-21 21:38, hash: 6f158f834d
Worked: 2.93 Final

Caused by 44d2479dc3

Short description of error
When using Eevee to render a viewport preview of an object containing a material with an (empty) normal map, the geometry gets transformed to its UV layout.
This only happens when the material contains a Normal Map node and "High Quality Normals" are enabled.

Exact steps for others to reproduce the error

Open the attached blend file:
Eevee_Bug_v01.blend
Switch viewport to "Rendered" or "Material Preview" (both using Eeevee)
The cube is transformed to its UV layout
Toggle the "High Quality Normals" option under "Performance"
See the cube switch from its UV representation to its actual shape
Toggle the "High Quality Normals" again
The cube changes its shape to a UV cross
