  1. Open the project, open the BasicBlurMap, press Play.
  2. Observe that the background blur is present.
  3. Enter command r.HDR.EnableHDROutput 1 to enable HDR output (even if it's not really supported)
  4. Since we're working with engine defaults, composite mode should be active already, if it isn't enter command r.HDR.UI.CompositeMode 1 as well.
  5. Observe that the background blur is gone.
  6. Enter command r.HDR.UI.CompositeMode 0.
  7. Observe that the background blur is back.
