** Description changed:

- Ubuntu 12.10 64bit (updated from 12.04) / NVIDIA GeForce 8 proprietary
- driver.
+ [ Impact ]
  
- This bug happens to me from 12.04 from some update I think.
- It appears mostly when I open a new application and only ocassionally.
- As temporary "solution" creating some other event like opening Unity dash or opening some next window, etc. fix it. Then window content is refreshed and I can see all correctly.
- Same with stable and experimental nvidia drivers.
+ With nVidia hardware from time to time window content is rendered black
+ or transparent.  The problem manifests more frequently as session uptime
+ increases.
  
- Screenshot of this bug is attached.
+ Apparently the problem was caused by textures being cached and not
+ freed, resulting in memory exhaustion conditions.  It turns out the
+ texture caching is unnecessary anyway.

+ [ Test Case ]
+ 
+ Verification requires an nVidia GPU with proprietary drivers.  The
+ problem can not be reproduced at will, only after some time (depending
+ on resident GPU memory and usage) and even then only randomly and
+ unreliably.
+ 
+ [ Regression Potential ]
+ 
+ It is unlikely this change has the potential to introduce new
+ regressions.
+ 
+ [ Other Info ]
+ 
+ Fix was cherry-picked from the Ubuntu "Vivid Vervet" dev relase where it
+ has been in use for some weeks without problem.
