System Information
Operating system: Ubuntu 18.04.3
Graphics card: AMD RX 580

Blender Version
Broken: 2.81 1252577580
Worked: 2.80.75

Short description of error

American Beech.blend
This glitched viewport happens if you append the tree object in a new project in 2.81.

Exact steps for others to reproduce the error
The glitch happens only if you never go in material or rendered modes before appending the object.
So, open Blender 2.81, let everything as it is by default, click on File > Append and append the "American Beech" and "Leaves American Beech" objects.
Switch to material preview or rendered.... the tree is glitchy.
But, if before appending the object, you switch to material preview or rendered mode and then append the two objects then you will see it textured correctly.

Can confirm.

Interestingly I can get around the glitch if I reduce the Leaves American Beech objects leaf particle system hair count to 772 or lower [carefully bisected this :) -- 773, and you have the glitch...]

Happens to us also in EEVEE, can not render few projects because of that : (
If there is a lot of objects in scene, shaders not fully update, till you click somewere or change frame.
It renders black and white images on batch render (renderfarm)
(tried latest builds, issue still exist starting from 2.81 till today)
