Force disable snapping windows

How can I reliably disable snapping windows? When I drag a window around by its titlebar and near the upper edge, it tints and wants to maximize if I let go of the mouse then (trying to park my app there, not cover the whole workspace!)

Until Unity becomes more productive for my work style I switched to cairo-dock with effects for now (which also is not without issues).

As the logged in user I have run ccsm the Compiz manager and disabled Snapping Windows altogether, and verified many times. Doesn't seem to care. Haven't filed a bug rep yet as maybe there's some other setting I don't know about. Nothing else results in the CompizConfig search when I try snap or snapping. Any other ideas?

Solution 1:

Disabled "Scale" under ccsm's "Window Management" .... and snapping to maximize suddenly stopped, finally! A lot of other things changed too, namely many updates since last month.

It would go such a long way if this plugin like so much else had a nearby description of what it actually does and when...not just "Scale Windows" on ccsm's left column and nothing else mentioned.

Solution 2:

My previous answer turned out to be wrong (not always off).

Finally found the answer! https://askubuntu.com/a/72480/38636

Seems it's also know as “drag to maximize” behaviour in Compiz and disabled in CCSM Grid plugin, Edges tab, Top Edge :: set to None.
