There is a haloing effect when depth of field is used while post processing also has propagate alpha enabled at higher scalability levels. The effect becomes more obvious as the resolution of the viewport is increased.
1. Download and open the "Reproducer" project from the UDN case (see addl info URL)
2. Start a PIE session. Observe that the DOF appears normal.
3. Then execute the command "r.PostProcessing.PropagateAlpha 1", and "sg.PostProcessQuality 4" in the console.
4. Full screen or increase the size of the viewport and the haloing effect should be visible.
