New window opens without content

[Armin2208]

Version: Windows 10 1903
UI appears after pressing Windows + Shift + S and leaving it.

Code:
DesktopBGui BGui = new DesktopBGui
{
Owner = GetWindow(this)
};
BGui.ShowDialog();

Opens just fine while running in visual studio debugging. But in the compiled release version outside of Visual Studio this happens.

Hi, @Armin2208.

Thanks for the feedback.
FluentWPF uses undocumented Win32API(SetWindowCompositionAttribute method).
This issue arises from the same causes as #42

SetWindowCompositionAttribute behavior is broken in Windows10 1903, so that I'm trying to avoid this behavior and support Windows10 1903.

Please wait for a while.

Hi, @Armin2208.
I fixed this issue, and released as FluentWPF 0.7.0.
Please, try it.
