Thank you for your answer, Michel!
Although not being a developer, from what I read so far everything
points towards X being the upstream part responsible for this issue...
Leaving the Scale Plugin aside, the ALT-TAB behaviour can't be a
Compiz issue, right? As far as I understand you, you don't want map
minimized windows yourself (in X) because of higher ressources needed?
Well, don't you agree at all it is a usability bug and there has to be
done something about it? Any ideas how to minimize the ressources
needed? For instance by not constantly refreshing minimized windows
like you do it with active windows, couldn't you save a lot of
ressources by just saving a "screenshot" (probably what you meant with
the last pixmap anyway)?
