How to reproduce:
1. Create a new project
2. Switch game view to Device Simulator
3. Select a device which has a notch, like Samsung S10e
4. Go to Player Settings > Android > Resolution and Presentation
5. Disable "Render outside safe area"
6. Keep "Start in fullscreen mode" enabled
7. Play the scene

Actual result: everything is rendered
Expected result: the area where is notch shouldn't be rendered

8. Disable "Start in fullscreen mode"
9. Play the scene

Actual result: after rendering around notch is fixed when running in windowed mode, notch area is rendered
Expected result: the area where is notch shouldn't be rendered (navigation bar is not rendered and that works correctly)
