[Bug 1506908] [NEW] Switching windows with 'Ring Swither' and using a 3x3 workspace array results in faulty switching between windows (window shifted) placed further than 2x2 workspaceses.


Public bug reported:

Steps to reproduce the bug:

- In ccsm enable Ring Swither to use alt+tab for 'Next Windpw Key (All
Workspace)'. Follow to disable the default key combination in Unity

- In ccsm's  'General Options' set 'Desktop Size' to 3x3.

- Go to workspace 3,1 (horizontal, vertical; starting from top left) and
grab any window by the title bar and drag it to the right edge so it
expands to the right half of the workspace.

- Navigate to workspace 1,2 using ctrl+alt+arrow keys and press alt+tab
until you see the window you just moved to workspace 3,1

- Release the alt-tab and you will be taken to workspace 1,1 (instead of
3,1) and you will see the right edge of the window on workspace 3,1 that
was shifted to the right for approx. 2-3cm for some reason

- Try other combinations
