I'm using B II for Window Decorations and Air for the Desktop Theme. Switching
to Oxygen Window Decorations with animation disabled still results in KDE
automatically disabling desktop effects.
It is the OpenGL compositing selection which is causing kwin to freak out, and
since Xrender works fine for the couple management effects I want (the rest is
just eye candy I usually disable anyways) I'll live with that for now (or
downgrade to 295.33 if the other user on this box complains :) ).
