[Android] Rotating device from portrait to landscape multiple times creates visual distortions

Mobile

-

Steps to reproduce:
1. Open "rotationBugEmptyStripped" project
2. Build and run"SampleScene" scene on Android
3. Rotate phone from portrait to landscape and back to portrait (the more times you switch between landscape & portrait mode the more visible the bug becomes)
The screen starts flickering before fully re-adjusting screen aspect ratio to correct one after rotating (inspect the attached video)

Actual result: half of the screen flickers after rotating the device just before the scene view is readjusted correctly
Expected result: Screen should rotate without any visual artifacts no matter how many times device is rotated

Note: This can be reproduced with a new project.
Note: Not reproducible on iOS (tested with 2019.3.0a8)
Note: Reproducible on Vulkan and OpenGLES

Vulkan and OpenGLES yields a bit different results
Vulkan: After each rotation, aspect ratio takes longer to correct itself but no visual distortions or flickering are visible
OpenGLES: After each rotation, the screen is split in two and one side starts flickering for some amount of time (the more times you switch between landscape & portrait, the longer it stays in that flickering state)
