DID NOT OCCUR IN BP FPS PROJECT - might be ContentExamples specific
This issue does not occur when forward shading is disabled.
Viewport error reads:
Additionally, entering in the following console command restores the image to normal
Entering in different values such as 2, 4, 8 with the above console command results in the black viewport with artifacting/corruption (see screenshot)
This is not a regression as the same issue is hit in 4.25.4
An ensure also occurs as mentioned by [Link Removed]
Result: Black viewport with artifacting when PIE
Expected: Viewport renders as expected
