Hi all As I known, when a window is fullscreen, desktop shell will create a black surface after it. If the window is transparent later, it shows a black screen. But the app developers maybe except it to be hide.
Just take QWindow function hide for example, app1 start app2, then app2 call hide, it excepts to show app1, but it shows the black surface of app2. - Does the desktop shell doesn't support set fullscreen surface to be transparent? - Thank you. Best Regards Nancy
