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.
