Description
Description: In some cases, the application cannot be ejected after being minimized
Environment: deepin v20，Window manager: KWIN
Steps: Kill the window manager, start the example program, open the window manager, and click minimize.
Reason: The application may be started before the window manager, and some window managers _NET_SUPPORTED may be changed. These conditions will cause the _NET_SUPPORTED obtained by Qt to be inconsistent with the window manager
