Title:
  slow fade effects make unity completely unusable

Status in “unity” package in Ubuntu:
  New

Bug description:
  A fresh install of ubuntu 13.10 is completely unusable on my Acer
  Aspire One netbook. All fade effects are extremely slow, which makes
  the whole desktop slow to a crawl. Because fade effects are present in
  both the dash and the HUD, ubuntu is not usable. It takes over 2 full
  minutes with the cpu at 100% for compiz to open the dash, opening the
  HUD takes slightly shorter, around 30 seconds.

  WORKAROUND:
  Use unity-tweak-tool to disable blur alltogether via Search -> General -> Background blur -> Off
