[Bug 1403867] Re: Desktop/wallpaper flickers dreadfully

 

I spoke too soon. Although it doesn't happen so quickly now, and the
ghosts left behing don't flicker anymore, the desktop eventually does
not get redrawn, leaving ghosts of what was on the screen behind.

Title:
  Desktop/wallpaper flickers dreadfully

Status in Unity:
  New
Status in unity package in Ubuntu:
  New

Bug description:
  Since 14.10 the only way to use the system is with apps full-screen,
  because the background/desktop is constantly flickering. If you close
  a window, it leaves flickering ghosts of itself, like a nightmare. See
  enclosed ogv file for an example.
