Problem1: error message when i tried to connect to the home network and see the shares, error message said "operation not valid or supported" something like that...Solution: installed gvfs-backends and gvfs-fuse, logged out and then back in, everything's working as it should.
Problem2: for some reason enabling the MATE desktop environment's default compositor (to get fancy shadows under the windows) caused choppy resizing animation on *SOME* applications, yeap, some, e.g Eye of MATE while other applications like pluma or web browser were fine.
Solution: you need to... either install another compositor, e.g compton (i have my compton.conf and a small guide on some post here) or from Compiz panel, choose the resize effect to be something other than live-window-resize.
