Android with physical keyboard dims whole screen when navigating

[AlexanderSjo]

Describe the bug

When navigating with a physical keyboard on an Android device it dims the whole screen and does not go away. This happens when i click on any key on a connected keyboard. This only happens on real physical connected android devices and does not seem to happen when running on virtual devices. I have tried on multiple different physical Android devices with the same result. Both on android version 13 and 14.

It is way more obvious when running RequestedThemeVariant="Dark"

See recording from Android device:

AvaloniaAndroidPhysicalKeyboard.mp4

See simple sample repo:

To Reproduce

• dotnet new avalonia.xplat -av 11.1.0-beta1 -o AndroidKeyboardSample
• Set RequestedThemeVariant="Dark"
• Connect a real Android device with a connected physical keyboard
• Click any key on the keyboard and see the screen go dim.

Expected behavior

Do not dim the whole sceen when using a physical keyboard on Android device. It ruins pictures and colors.

Avalonia version

11.1.0-beta1

OS

Android
