2. Set the Screen Percentage to 25%
3. Run PIE
4. While in PIE, change the Engine Scalability Settings to Medium
5. While Running back and forth with the character, observe the ghosting to the lower right of the character. The columns through the level are a good place to observe the issue.
6. If the issue is not observed, change the Engine Scalability Settings to Epic, then back to Medium, without exiting PIE. Repeat step 5.
7. Execute the console command "vis DistanceFieldAOHistory".
8. Observe the same ghosting in the DistanceFieldAOHistory buffer.
