I haven't used Cinnamon since my first Linux install. That was ver 1.4. I don't think Cinnamon fully supports transparency yet, even with ver 1.6 or whatever is newest. I really don't know. I moved on to KDE. So many more things to adjust you can get lost. It all works, it is not a resouce hog and if you are running new hardware, who cares about this piddly stuff anyway. I like pretty. I like KDE. Here is a thread though: viewtopic.php?f=208&t=97101
