Tessellation used on BSP causes severe graphical glitches on AMD Radeon 200 Series cards.
The Licensee also mentioned it occurs on the Nvidea GTX 970 (not tested)
1. Download the attached project & open it
2. The error is visible in the viewport, PIE, or Standalone
Results: On an AMD card, tessellation on a BSP has severe graphical glitches
Expected: For the tessellation to work the same as it does on an Nvidia card (which isn't great because it's on a BSP but it doesn't have the flickering graphical issues as the AMD)
