Hello Greg,
I'm afraid that guest support of Compiz is still rather "work in
progress", but see below.
Gotcha. It is probably a fairly good stress test for both the VM
software and any GL implementation.

This leaves the full-screen issue: It turns out this issue occurs
using
Compiz, but not when using Metacity. No UI updates at all in
fullscreen - if
I type into a guest window the text does not show up. The cursor

even blink in a terminal window. However, the mouse cursor still
changes
when hovering over 'interesting points' (eg for window resizing),
and it
appears that I can move a window - but the UI won't be updated.
You might want to open a bug ticket for this, or search for an
existing one.
I was looking around for that the other day; how do I file a ticket?
Two other notes on Compiz's behavior as a guest:
1. Guest running 'glxgears': The gears do not show up in the box.
Once I got
them to show up in the lower-left corner by toying around with the
window,
and once they showed up in the box after switching between Firefox
and
VirtualBox windows on the host. Thus far cannot reliably reproduce
either.
Again, you might want to open a bug ticket, although I'm not sure
whether running openGL applications under Compiz is supported for now
(I'm not even sure whether it is supported on physical hardware using
legacy DRI).
Do you know if there is work ongoing implementing a DRI2-compliant
virtual video driver, then? If not, is the current implementation part
of the OSE edition?
If it's open-source and nobody else is tackling the DRI2
implementation, I can at least take a look (I can't commit to anything
immediately.) This kinda code seems like it's stuck in the glue
between guest and host machines, so I'd likely need to pick your
brains on quirks in developing in this environment. But it sounds like
an interesting project.
2. Guest running Compiz: The menus appear an update or so behind - it
honestly looks like it's somehow missed the last frame swap on a
double-buffered visual.
As above, but I don't know if this is a VBox issue - I sometimes get
the
same thing when I use Compiz on physical hardware.
It's 100% consistent, though. I haven't seen the issue in any of my
(limited) exposure to Compiz on physical hardware. This might just be
obviated by the DRI2 question above, though, so screw it for now.
Cheers,
Greg

Michael
