Platform: 10106.0.0 (Official Build) dev-channel eve

Steps to reproduce the problem:
1. Connect a monitor (HDMI/VGA to USB-C)
2. select Extend Monitor
3. Move extended monitor to different places around the main monitor and open Android Apps on the extended monitor
4. Android Apps are black (full screen) or transparent (windowed)

What is the expected behavior?
Allow using Android Apps on extended monitors, when monitor is position up/down/left/right

What went wrong?
Hi

i'm using a Philips 247E6 monitor connected via HMDI (via dodcool USB-C hub)
All works well, resolution, screen overscan etc.
When using as mirroring all is OK
When using Extended display, Android Apps are showing as black screen when in full screen mode, or completely transparent when windowed.

I noticed that only when the monitors setup is as the image below, I can use Android Apps on both screens.

All other combinations are no good (I always prefer the extended window to be on top as I use them vertically)
On chrome apps / browser etc. all is OK

I tried with a different monitor (this one with VGA) and the same happens

Did this work before? N/A
