Mutter version 3.36. Bug summary When using the GNOME magnifier feature ghost copies of dialogues such as the Alt+F2 window or the password prompt appear if the magnified view moves away from the dialogue. Steps to reproduce 1. Enable GNOME magnifier by pressing Supper + Alt + 8. 2. Press Alt+F2 to open the command dialogue. 3. Use the mouse to pan around the screen.
