The Metacity
window manager has
a wireframe mode for when you move and resize windows. When wireframe mode
is turned on, only the outline of windows is displayed when you move and resize
windows. The contents of the window do not need to be updated during the move
or resize. The contents of the window are displayed when the move or resize
is complete.
To turn on wireframe mode, run the following command:
# gconftool-2 --type bool --set /apps/metacity/sun_extensions/wireframe_move_resize true
