Screenshot of the problem.

When window decorations are removed by setting the _MOTIF_WM_HINTS property on windows, mutter does indeed remove the borders by incorrectly keeps clipping the window with the decoration mask.

Steps to reproduce:

1. Launch, e.g., gnome-calculator.
2. Remove decorations via:

    xprop -name 'Calculator' -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x0, 0x0, 0x0"

Results:

See attached file. Left and top of window is clipped off.

Expected results:

A rectangular window.

Note:

I make use of this technique (via devilspie) to keep a Xephyr window on one desktop running an old GNOME session in a VM for development. At the moment I have a 'magic border' of ~10px around the top-left which is still active and goes through to the underlying Xephyr but is clipped by mutter. Very odd!

Since window->frame_bounds is used as a cache we need to invalidate it when
destroying the frame.
