Description

This issue has been observed in 4.18.3 as well as 4.19. See attached screenshot showing scene from 4.18 on Nvidia, compare to attached GIF showing same scene on AMD card.

Steps to Reproduce

On machine with AMD GPU:

  1. Open new empty level
  2. Select 'Floor' static mesh
  3. Scale up to 10000x10000 in X and Y
