Tablet button mapping overlay appears over top of lockscreen
If the Wacom Tablet panel's "Map Buttons..." helper overlay is left open and the machine allowed to lock, the overlay will still be present and drawn over top of the lockscreen when the computer is re-awakened. Pressing ESC closes the helper as expected, and other keyboard input goes to the lockscreen as expected, but the visual effect is jarring.
Steps to reproduce:
- Connect a Wacom tablet with ExpressKeys
- Open GNOME Settings
- Go to the Wacom Tablet pane
- Switch to the "Tablet" tab
- Click "Map Buttons..."
- Wait for the computer to lock
- Wiggle the mouse or press a key to re-awaken it
- See that the button mapping helper is drawn over top of the lockscreen
