[Bug 374642] Re: high cpu usage viewing pages that contain .gif images (nvidia driver, opengl and antialiasing settings related)

[sterios prosiniklis]

** Description changed:

  Jaunty running from a Live cd, nvidia proprietary driver and extra visual 
effects enabled
  On this page http://www.wdvl.com/Multimedia/Animation/GIF/Examples.html
- the cpu usage is almost 100%, when in nvidia xserver settings the opengl and 
antialiasing settings
+ the cpu usage is almost 100%, when in nvidia xserver settings, the opengl and 
antialiasing settings
  are set to sync to vblank,allow flipping and 16x respectively (or in an other 
combination of high quality settings).
  Problem does not occur when .gif images are filtered with addblock or when 
nvidia xserver settings are set to default values.
  Quantity of .gif images seems not to be relevant, same results in pages with 
less animations.
  Same behavior exists in hardy normal installation, intrepid wubi installation.

  where the .gif image (not animated) if not filtered, creates the same problem 
in hardy. Intrepid and jaunty are not affected.
