Wobbly Windows extention for gnome shell.
For Gnome shell users, please activeate this extention via https://extensions.gnome.org/extension/669/wobbly-windows/
To avoid 'tearing' in the graphics alter the file /etc/enviornment to add the following lines:
CLUTTER_PAINT=disable-clipped-redraws:disable-culling
CLUTTER_VBLANK=True
Please note that alt-f2 and restart ('r') is not enough to apply the /etc/environment changes. Please restart your computer after you make that change.
