Shadows blinking/artifacting when rendering Directional Light Shadows

-

How to reproduce:
1. Open the project from Edit section labeled "Download: "
2. Set Active Scene to "WoundWormsLair_Light"
3. Enter Play Mode and watch Scene View

Expected result: No shadow artifacts or blinking
Actual result: Shadows flicker randomly into artifacts

Reproducible with: 2019.4.0f1
Could not test with: 2018.4.28f1, 2019.4.13f1, 2020.1.9f1, 2020.2.0b7 (project breaks when upgrading or downgrading)

Notes:
Only reproduced when rendering directional light shadows – not point or spot lights.
The hunch is that this bug is caused by a combination of multithreading and heavy load (i.e. many simultaneous shadow computations).
When running the editor with -force-gfx-st -force-gfx-direct the blinking disappears.

  1. Resolution Note:

    Not enough information, no repro project
