Open two windows of an application on Raring
Press Super+W to enable spread.
Observe that the windows shrink vertically and repaint when entering spread and re-expand when leaving spread.
I expect the windows should scale and not repaint or resize when entering or leaving spread.
Test case #1.
Start a virtualbox VM (with guest additions enabled so desktop resizing is automatic)
Maximise the virtualbox window.
Open a terminal in virtualbox and run the following command:-
watch xrandr
This will show the current resolution (which on my 1080p desktop is 1855x1034) - attached max.png
Enter spread on the host with Super+W
Observe the guest repainting the desktop
Wait a second or two for xrandr to display the new resolution (which on my machine goes to 1855x1006 - a reduction of 28px) - attached spread.png
Exit spread and observe the screen size goes back to what it was before.
Test case #2
Open a terminal
Enter the following command in the terminal
watch -d -n 0.5 "tput cols && tput lines"
Maximise the window
Press Super+W
Observe the number of lines is reduced by one when switching to spread, and increases back up again when leaving spread.

The resizing issue also occurs when minimizing and maximizing VMware windows. Window resizes and causes the guest VM to resize as well.
