DistanceFieldAOHistory introduces ghosting at low scalability and low screen percentages. This can lead to AO artifacts and a ghosting effect from the character.
This issue was also observed on //UE5/Main, CL: 35572048
1. Download the Licensee test project and open.

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.
