Description

System Information
Operating system: OpenSUSE Leap 15.1
Graphics card: NVIDIA Geforce RTX 2070

Blender Version
Broken: (example: 2.81 stable)

In scenes containing particle hair, viewport will render as nearly solid-white or solid-black in Material Preview mode or Eevee rendered view

Exact steps for others to reproduce the error
This is the smallest scene with which I've been able to recreate this. http://mrpendulum.com/MaterialLightingBug.zip

Open this scene, ensure Eevee is the renderer. Switch viewport to Material Preview or Rendered view. Also occurs if render engine set to Cycles, and Material Preview mode is selected. But does NOT occur when set to Cycles and Rendered view.

When issue is occurring, no longer occurs when performing either of these options. And won't reoccur until Blender is closed and reopened.
a) selecting an object
b) opening a new default scene, displaying eevee rendered, then reopening the above scene.

Pretty sure this has the same roots as T71552: Material view and Eevee Rendered View display glitch when scene contains hair particle systems with high amount of instances.

Same as in above report, you can get around by reducing the number of emitted instances...
Still needs to be looked at though...
