Description

Depthfade will not work properly on some Android devices If separate translucency is enabled. In the case of the attached project, drawing near the material using depthfade is strange.

This issue probably only occurs on Adreno 5xx device. It does not occur in the editor.

If using r.Mobile.AlwaysResolveDepth 1 or not using depthfade, or not using separate tranclucency, the issue does not occur.

Steps to Reproduce
  1. Open attached project
  2. Create android package
  3. Play the package on Android ( Adreno5xx )
  4. Rotate camera using virtual game-pad
  5. You can see black ghost near the sphere
