Hey t3g.
As a Fluxbox and Openbox user, I may not have as much experience as you do on
these desktops. May I please ask a few questions?
Cinnamon: I believe Cinnamon is GTK3/Gnome3-based. Doesn't Cinnamon use 3D
rendering? If so, isn't that the same problem as Gnome-Shell for those
without free drivers? I've also heard that their compliance with the latest
GTK has not been a priority. What do you think?
Mate: I've never thought of Gnome2 as a "light" desktop environment. Perhaps
it is compared to the latest KDE & Gnome-Shell. Also do you think it will
begin developing incompatibilities with GTK3-based applications? (Not
currently but moving forward?)
Is there a light DE which uses GTK3? I believe LXDE and XFCE use GTK2 as
well.
Thanks for your time.
