Yes - funnily enough a week or so ago I came to the same conclusion
about composited windows. So, we've made the fixes we needed to to both
the GenericAUView (the code of which is in the SDK) as well as our
custom views.
There is a composited option with AU Hosting - in fact, the default
window for AU Hostingnow is a metal composited window, as we see all
kinds of problems with backgrounds as well.
Also, in AU Lab we have an option to make the host windows composited
as Airy describes. One of the features you get for this is that the
window can actually put your view in a scroll pane - we also have this
kind of logic for cocoa views as well - though there you can specify
with a cocoa view which dimension of the cocoa view is resizable...
We'd be happy to look at ways of extending the logic around these
features.

seemed not interested at this time :-(
Things are so much easier with compositing...
The only hosts I know that can support compositing are :
- AU Lab (which makes me think there is still hope...)
- CVS version of SynthTest

ps : Peter, augui should support both compositing and non compositing
with no extra work. If there is a problem with some augui controls,
you can fill a bug ;-)

I don't think that there's a single AU host that provides
compositing windows for AUCarbonViews. Hardly any AUs out there
have AUCarbonViews that work correctly in compositing windows. I
wish that this had been specified from the start, that AUCarbonView
windows must be compositing, or at least the views should support
compositing, cuz compositing windows work much better. But
unfortunately now there's a situation where we're probably not going
to be seeing hosts use compositing Carbon windows for a long time
cuz of widespread non-support among AUCarbonViews...

I just spend the last couple of month converting my Cocoa UI to
Carbon with the help of AUGUI and a lot of custom HIView stuff,
i felt i had to abandon the Cocoa UI since there was to few hosts
and the behavior was not the same across Cocoa UI hosts,
i even had a way of using Cocoa UI in Carbon only hosts.
Even though it was a very good learning experience there was a lot
of reinventing the wheel compared to using Cocoa.
While testing i used the AudioUnitHosting.app that only supports
non compositing windows and i also tested with Logic
and a few other hosts and everything was fine, but before releasing
i just checked with compositing on and it was not working :(
so a list with what type of UI the hosts use would be a very nice
aid in determining what to support.
The best thing would of course be if there was only one type of GUI
, since the GUI is the most time consuming part of an AU, it's
very difficult to maintain several different types with small hacks
for all the different hosts.
