Desktop based viewport switching with wall causes mouse issues on some windows

[Doug McMahon]

Binary package hint: compiz

This is a fairly limited use case bug atm (very late here) could maybe affect more
If Desktop-based viewport switching is enabled with the default wall plugin then it's possible to lose scrolling and mouse clicking on some windows.
Saw this immediately upon the upgrade today on a newish install that I've kept at default settings - to confirm wiped the install, did a fresh iso.
Updated all but compiz/unity, enabled Desktop-based viewport switching, no issues
The upgrade of compiz/unity (shows also on Classic so not unity) showed some issues

The clearest example would be to open synaptic, search something and then try to scroll thru the returned package list
Instead of scrolling the list, the viewports will be switched
Picking up the window and moving around can allow scrolling to occur

Then when trying to mouse click on a package same thing - no response unless the window is moved about. Trying to get and then scroll in a changelog, same thing
The install I removed showed similar in other areas (no mouse click, ect., too late to explore this install further

Switching from wall to rotate eliminates all such behavior, works quite fine (am on rotate right now.
Because of similar language thought this fix might be related, don't think it is ( tested by rebuilding and reverting that patch, no change
bug #734250
(am reporting with the repo packages re-installed
