2. Open "TestScene" scene
3. Change the platform to iOS or Android
4. Press Edit > Graphics Emulation > OpenGL ES2.0 or OpenGL ES3.0
5. In Hierarchy select "ParticleSystem" gameObject or enter to Play mode
Expected Result: Particle System or Scene runs without warnings
Actual Result: Following Warning appears in the Console:

Notes:
- This issue appears on iOS and Android platforms
- This issue only occurs when both PartialScreenCamera's have the same Viewport Rect
Reproduced on Unity 2017.4.0f1, 2017.4.29f1, 2018.1.9f2, 2018.2.21f1 and 2018.3.0a1

Resolution Note (2017.4.0):
The warning is not shown in newer versions of Unity because graphics emulation functionality is gone.
The warning is legit in the provided setup.
