Mmm, I have 12.04 at home on my laptop and have not had the problem, I
will check and see that kernel level it is, though I normally apply
updates when they are offered.

I have experimented a little more today. I powered off and waited a few
minutes, then on again and no smearing, even having started Nemo. And I
even got my desktop image. About an hour ago Evolution got stuck so I
closed all my apps, logged out and back in again and got smearing. I can
tell because the Unity side bar and edges of the screen sometime have a
line around or at one edge.

Just now I powered off again, and went to make coffee. When I came back
I switched on again and no smearing (but no desktop image, just black).
Let me just start Nemo ...   argh, smearing is back! Still not convinced
it has anything to do with Nemo though.

Title:
  Ubuntu 13.04 Unity desktop background smears when dragging windows

Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  In the last week I have found that my desktop background is not
  refreshed when I drag windows across the screen. This also happens
  when windows are minimised or closed. It is especially noticeable when
  compiz animations are used as the window shrink/blur remains on areas
  of the screen where only the background shows. It has been reported on
  AskUbuntu with the title of 'Unity desktop "smears" (doesn't refresh)
  and shows no wallpaper' and one contributor says it doesn't happen
  with Cinnamon (though their post was deleted as not being an answer,
  as was mine). My wallpaper does not show either, even after I changed
  it, and it used to.

  My hardware it AMD A10-5700 with 7660D graphics on Ubuntu 13.04 with
  latest updates. I am using the fglrx-updates driver.

  Others (on AskUbuntu) tried different graphics drivers but it didn't
  help. I have not tried with 13.10.

  Screen shot attached.

  Thanks.
