Picture showing a "phantom" composited window frame, where the frame is composited, but no window is shown.
Description of problem:
Some QT4/KDE4 applications that make use of the notification-area (such as Amarok), while used in GNOME with Metacity as the composite-manger, and composite enabled, there is a "composited frame" with the drop shadow of an "invisible window" (screenshot)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start a GNOME session, install gconf-editor.
2. Enable Metacity as the compositor.
3. Start a KDE4 application that makes use of the notification-area (like Amarok)
There is an area that a window would take up which is drawn composited, though there is no window frame (see screenshot)
The desktop to remain clean when a window frame is not meant to be shown (not composited).
We don't support the metacity compositing manager; there's no UI to enable it and we don't see it as being an interesting long-term direction for compositing; if it still happens with F12 you might want to file a bug against Metacity upstream.
