3. Enter and exit the Play Mode multiple times
4. Open Window > Analysis > Memory Profiler
5. Click on the “Capture New Snapshot” and then the “Take Snapshot” buttons
6. Select the generated Snapshot and go to the “Unity Objects” section
7. Write in the search bar “TAA”
8. Observe the number of objects in “RenderTexture”

Expected result: There are no TAA objects in “RenderTexture”
Actual result: Amount of TAA objects in “RenderTexture” increases each time the Play mode is entered
