Foliage Disappears Using OpenGL4 in Packaged Game

Foliage Disappears Using OpenGL4 in Packaged Game

Description

This issue cannot be reproduced in 4.18 but can be reproduced in 4.19.1 as well as Main (CL 3998250) therefore I am marking this as a regression.

Steps to Reproduce
  1. Create new project from Blueprints sample (Launcher 'Learn' Tab)
  2. Enable OpenGL4 in Project Settings
  3. Paint some foliage on ground somewhere (project has 4 grass meshes)
  4. Package game
  5. Open packaged game with -OpenGL4 command

Result: When standing in the middle of the painted foliage and rotating camera, some plants disappear and screen flickers. This does not happen when the program is started without the -OpenGL4 switch

Expected: Foliage will not disappear, screen won't flicker.
