Generated texture coordinates missing when switching from solid to rendered mode

Description

System Information
Operating system: Windows 10 64 bit
Graphics card: Nvidia GTX 750 Ti

Blender Version
Broken: 2.80.0-git.14884cda1ff5-windows64
Worked: 2.79b f4dc9f9d68b

Short description of error
The "Generated" texture coordinates make textures "stick" to the surface, even if the object is being deformed.
However, this does not work as expected in 2.80 with the Armature Modifier, neither in Eevee nor Cycles.
In 2.79 in works correctly.

Possibly related: T59275.
However, this bug affects both Cycles and Eevee, while that report only concerns Eevee (and Cycles works correctly).
The difference is that here an Armature is used, while that report uses Shape Keys.

Exact steps for others to reproduce the error

The scene contains a cube with an armature modifier.

  • Open in both 2.79 and 2.80.
  • Press F12 to render.
  • See how the texture mapping differs.

Since the main issue is fixed and the remaining issue involves rather tricky depsgraph changes, I no longer consider this a blocker for 2.80.
