I can confirm that previous comment. On my hardware with 108 I see the
launcher as either gone (transparent textures) or partially corrupted.
Various other textures are sometimes broken but the launcher is
consistently affected.

Bug description:
  [Impact]
  This bug basically makes NVidia machines unusable after suspend. This is causing problems for users and OEMs that want to use 11.10 alike.

  [Development Fix]
  https://bazaar.launchpad.net/~unity-team/unity/trunk/revision/2205

  [Test Case]
  .
  To reproduce:
  1) Suspend
  2) Resume
  2a) login, if necessary. Note that the login screen (lightdm) displays properly
  3) Notice the corrupted launcher
  4) Mouse over the launcher; the launcher redraws and the corruption goes away

  [Regression Potential]

  Low. We have tested the fix in the development version that we're planning on releasing in April 26th and have found no problems.
  With the big diff, the regression potential might be a bit bigger for precise.

  == Original Report ==

  The unity launcher is reliably corrupted upon resume from suspend with
  some (all?) NVidia hardware with the proprietary NVidia driver. All
  other visual elements seem to draw correctly, it's just the unity
  launcher that has this problem. The launcher looks fine after it
  redraws (for example, if you mouse over it).

  The problem is not reproducible on Intel or AMD graphics hardware, and
  I'm told (by Ted Gould) that it doesn't affect the nouveau driver. I
  have not tested the nouveau driver myself.

  This problem been reported several times in the comments of bug
  676166, I'm filing this separate bug for clarity since 676166 is
  overloaded.

  To reproduce:
  1) Suspend
  2) Resume
  2a) login, if necessary. Note that the login screen (lightdm) displays properly
  3) Notice the corrupted launcher
  4) Mouse over the launcher; the launcher redraws and the corruption goes away

  The problem affects 11.10, and is not fixed by upgrading to more
  recent unity, compiz, or nvidia drivers from oneiric-updates or even
  the most recent SRU candidates not yet in oneiric-proposed. Currently
  I have the following installed and the problem still exists:

  ii  nvidia-common                             1:0.2.35.1                                 Find obsolete NVIDIA drivers

  ii  nvidia-current-updates                    285.05.09-0ubuntu0.1                       NVIDIA binary Xorg driver, kernel module and VDPAU library

  Compiz SRU candidate (not yet in -proposed):

  Hardware is a MacbookPro 3,1 w/ NVidia 8600M GT. I'm using the amd64
  build of 11.10.
