When opening the Stack-O-Bot project in 5.0 Preview 1, the project has a rendering issue where bright shimmering lights appear all around the screen. I discovered that this is due to the PostProcessVolume as deleting it causes the issue to stop. More specifically, within the PostProcessVolume settings it seems the Final Gather Quality setting under Lumen Global Illumination is the cause as disabling the setting also fixes the issue. A video demonstrating this issue can be found here: [Link Removed]

Tested in //UE5/Release-5.0-EarlyAccess @ CL 16682836 and this did NOT occur, so marking as a Regression.

Steps to Reproduce
  1. Download the Stack-O-Bot project
  2. Open the project in 5.0 Preview 1
  3. Move the camera around

Severe graphical glitches appear throughout the map

The project loads without any rendering issues
