> any update on this?

Yes.  I have run through testing this on various combinations of
graphics cards and video drivers for both natty and oneiric while
running Unity.  In this testing I was able to reproduce the bug only
with fglrx-installer and the old nvidia-173 proprietary drivers.  The
free drivers worked properly.  The nvidia-current driver worked fine as
well, even in natty.

Thus, I confirm Pitti's earlier statement that this is an fglrx specific
bug.

As a next action for this bug, Canonical will escalate to AMD.  There is
insufficient time remaining for a fix to be included in oneiric, but we
may be able to provide an updated driver via x-updates; as of oneiric
jockey (aka 'Restricted Drivers') will be able to load driver updates
from this repository.

No promises for earlier Ubuntu releases, however if we provide driver
updates it will be via the x-updates PPA.  Otherwise, you can download
and manually install new drivers from AMD directly, but note these are
not supported by Ubuntu.

Alternatively, the open source -ati driver supports the full range of
ATI chipsets; it doesn't have as rich of 3D support as fglrx but it has
sufficient support to run Unity reasonably well.  So as another
workaround you should be able to disable fglrx and run using just the
open source driver.

Similarly, for those users on older NVIDIA hardware not supported by
nvidia-current, the -nouveau driver is available, and as of oneiric also
supports 3D unity.  It also lacks the level of 3D support that the
proprietary driver has, but is sufficient for running unity.

And of course, Unity-2D remains a suitable workaround.

We had also considered the option of dropping Vino from the distro
entirely.  However I think this is unnecessary; the bug seems localized
to just certain video drivers, and there are multiple ways of working
around it.  I also am hopeful we can get a fix for fglrx in the not too
distant future.  This seems like a handy feature and would be a shame to
lose it over what appears to be just a single driver bug.
