Opacity settings fail to work on startup

Is there an existing issue for this?

Current Behavior

Every time I start CP Editor, the main window becomes completely opaque, even if I have set the transparency in the settings before.

To make the windows become transparent again, I have to set the transparency argument in the settings manually every time after startup.

Expected Behavior

After setting the opacity, the main window can be transparent depanding on the settings every time after start up.

Steps To Reproduce

1. Set the opacity argument in the settings to make the main window transparent.
2. Close CP Editor.
3. Restart CP Editor. The main windows become opaque.

CP Editor Version

7.0.1.r3.g21813202

OS

Desktop Environment: GNOME 45.4

I don't know whether this bug is related to the desktop environment or not. 🤔

It works as expected on my i3wm. As I remember, also on KDE Plasma (several years ago).

You can try setWindowOpacity again (or only) in the QTimer::singleShot in AppWindow::finishConstruction 🤔

By just commenting out setWindowOpacity in the construction function of AppWindow (https://github.com/cpeditor/cpeditor/blob/master/src/appwindow.cpp#L107), it works as expected. 🤔
