[Bug 290849] Re: [i915GM] Short-lived display corruption with compiz on Intrepid

[Bryce Harrington]

** Description changed:

  On my desktop with nvidia hardware, running xcompmgr with openbox I
  always noticed that when windows first appear (especially complex ones
  like Firefox/Thunderbird) you get a moment of either garbage or some old
  framebuffer after the wm brings the window up and before the app fills
  it.  I'd always noticed by contrast that my much less powerful Intel-
  based laptop running 8.04 with Compiz was as smooth as butter.  I saw
  this effect very occasionally, but generally performance was good.
  
  Having upgraded to the latest 8.10 on that laptop, I really notice that
  when opening Firefox or Thunderbird I get that same effect almost every
  time in quite a pronounced way.
  
  I tried to capture with xvidcap without success, but managed to grab
  photos of the effect, which are attached.
