I am currently working with QT/QML. The product I am programming is only for windows based. so, I am going to use winui3 (not considering WPF, WinForms, and MFC. they are not easy to use C++ or very old).
As you probably know, winui3 can be developed with WINRT/C++, it looks like almost UWP. I have tried to display VTK render window with having the red background color on the MainWindow.xaml. but when the software is launching and closing, I can see the red background in a very short time and be expected the red background is hidden on the main window.
could you let me know how to avoid this. if someone has had experiences about WPF and VTK C++, I expect the similar solution may be applied.
