[Matthias Niess <729979@xxxxxxxxxxxxxxxxxx>]

I updated the description with the workaround instructions on how to
reproduce. According to the related branches the apparent fix was merged
into Compiz 0.9.8. I have 0.9.9 (raring) and it is not actually fixed.
Was the fix removed again from 0.9.8 or is this wrongly marked fix
released?

** Description changed:

  Binary package hint: compiz
  
  When switching focus from one window to another, the target window may
  become blank. See the attached screenshot, where I opened two gnome-
  terminals and clicked on their titlebars alternately - the issue was
  triggered after about 5-10 clicks. I've had this happen on other
  appications too, e.g. software-centre, empathy, etc.
  
- Doing shade+unshade, maximizing or clicking away from the problematic
- window usually makes the window contents come back. The window remains
- responsive to both keyboard and mouse (by the way, in the screenshot the
- mouse cursor was an I-beam before I pressed PrtScr).
+ HOW TO REPRODUCE:
+ 1. Minimize a window
+ 2. Initiate Scale and deactivate it again (press Super+W to show all windows and then press it again to go back to normal)
+ 3. Click the window icon on the launcher to maximize it again.
+ 4. The window contents will be white or black depending on the Ubuntu version
  
- This is on up-to-date natty, installed from scratch using the daily
- image from the 1st of March.
