Daniel, thanks for pointing to 862430 since I was affected by the recently duped 876198. However for this one it might be worth extending my comment #2 where my notebook (unity+wall) isn't affected by the flicker while it has the same graphics card as the op [Mobility Radeon HD 4200 Series] [1002:9712], using open source radeon driver here, instead of Acer it's a HP 625 and it was a fresh alpha installation instead of Oneiric upgrade.
