No reason occurs to me why redundant changes shouldn't be discarded in
the case of alpha-background, but modifications to other parameters
(e.g. Qfullscreen) always trigger recomputation of various window
manager properties and states, which is not redundant when these
properties change without Emacs's knowledge.
