Composite but not stupid

A little feature that comes really, really handy surfaced after the backporting/ updating of MATE the other day.
There is an option to enable the composite manager, and be able to, for instance, have my beloved drop shadow effect, but ITOH, to disable the dreadful creation of thumbnails when you circle thru windows with Alt + Tab, something that slowed the whole thing dramatically, to the point that, in the old GNOME 2, it became useless...
I was looking for an option to do this nearly five years ago...

• Metacity composite: can I disable thumbnails on Alt+Tab?

So, I guess, change -and new- is good!
