Problem Description

Screen flickering when plug in/unplug USB keyboard/mouse to Android device.
It happens only with AIR applications and interrupt smooth UX in cases when users need to plug in/unplug USB keyboard/mouse.

Tested with multiple AIR versions, even with latest AIR 33.1.1.889 with multiple different Android devices with different OS versions and architectures with different USB keyboards/mouses.
Same problem in all cases.
It works fine with non-AIR applications.
There is no such issue with USB cameras.
There is no such issue with Windows/macOS devices.
renderMode and containsVideo values no matter.
