screenshot of Google Earth under Gnome fall-back mode

The OpenGL content is not displayed correctly in Gnome fall-back mode. Only
right up corner of the content is available. When the window is dragged the
position of available content is fixed, and the other part keeps black or
nothing. For example, when the Google Earth window is dragged to the right part
of the screen there is no 3D content displayed in the window.
The same problem happened with glxgears, glxspheres, etc.
While glxgears can be seen when the window is inside a very small region of the
left up corner of the screen, glxspheres can displayed when the window is
inside a much larger part of the left up part of the screen.
