Steps to reproduce the problem:
1. Launch Terminal
2. Install a GTK app like gedit. Also tested with nautilus, gnome music, etc.
3. Launch gedit. Before closing, maximize the window.
4. Try and launch gedit again. Entire content area of window is transparent. You can tell it's there by right-clicking, as you see the proper context menus.

What is the expected behavior?
Apps should display correct content even when maximized.

What went wrong?
You can resize the windows manually to fit the full screen and close/launch without issues. It's only when the windows are maximized before closing issue appears.

Did this work before? N/A

Doesn't seem to apply to QT apps. Or apps that "reset" the window size (for example, if you maximize the window before closing, and the app launches at whatever the default window size is when you re-open it.)

If you can get it to launch non-maximized again, sometimes by constantly closing/opening it, sometimes by using sommelier, sometimes by uninstalling/reinstalling, the app will work fine again.
