OrbTk widgets example doesn't work with Windows 10 new screenshot method (snipping bar)

[arctic-alpaca]

Hello

Describe the bug This bug only appears when using WindowsKey-Shift-S to take screenshots using the snipping bar as described here. When the orbtk widgets example is the focused window when pressing the key combination, the snipping bar isn't able to take screenshots. Taking screenshots of the orbtk window works when any other window is in focus. This means the "take a screenshot of this window" function of the snipping bar also doesn't work with orbtk. When the orbtk window is in focus, no screenshot is possible, not even of an area outside of the orbtk window. Taking screenshots with the snipping tool works as expected, even using the "Window snip" to take a screenshot of the orbtk window.

To Reproduce Steps to reproduce the behavior:

1. git clone https://github.com/redox-os/orbtk.git
2. cd orbtk
3. cargo run --example widgets --release
4. focus the orbtk window
5. press WindowsKey-Shift-S
6. take a screenshot
7. open paint and press ctrl-v
8. nothing appears

Expected behavior A screenshot should appear in paint.

Screenshots Kinda the issue.

Desktop (please complete the following information):

• OS: Window 10 home 1909

This bug doesn't seem to be present in alpha3.
