Foliage Disappears Using OpenGL4 in Packaged Game

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.

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.
