** 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.

Bug description:
  [ Impact ]

  With nVidia hardware from time to time window content is rendered
  black or transparent.  The problem manifests more frequently as
  session uptime increases.

  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.
