Done some investigating try Preferences
click on Windows
check "Don't show window content while dragging"
. It worked for me.
Above does remove windows animations but produces another animation whem moing windows around; it's not a fix. The fix is to use the configuartion editor.Menu
> Configuration Editor
alt F2 type in mateconf-editor
then click desktop
That should work it works on my system LM 13 MATE.
***No need to install gconf editor as Mate comes with the mateconf-editor
