[Bug 1009201] Re: lagging while scrolling a page.

[Praveen Thivari]

** Description changed:

  Firefox doesn't scroll the page properly.
  
  I may not be able to explain the problem exactly. But here is what
  happens :
  
  1) Open certain website. For Eg: ubuntuforums.org
  
  2) Try scroll the page down.
  
- 3) On screen it looks like it is not scrolled but in fact it would have scrolled down. 
-      This is confirmed after sometime when the page come out that freeze and begins to show the new position of page.
-       Also it can be confirmed by trying to copy a line or opening a link. The link will not be opened because the link would have scrolled to new position and after the window comes out of the 'GRAPHIC FREEZE' you can click on the link from it new posiiton.
+ 3) On screen it looks like it is not scrolled but in fact it would have scrolled down. Ie It appears like GRAPHIC FREEZE. I say it as graphic freeze because I can use the window, for that matter refresh the page etc.

+ Also to be noted is that this problem occurs randomly.
  
  It creates a very jarring experience.
  
  Looks like problem is with Ubuntu/Unity. Because on linux mint this
  problem is not there
