I am affected by this bug to on Ubuntu Mate 16.04 LTS.
Please test in combination with activated compiz affects.
After switching to compiz It was not possible to change the number of wokspaces.
-The actual number of workspaces always stays at 4, but shows number 1 when looking in the panel Setting.
-Resetting the compiz settings did not help
