Bug Description

My config:

- HP 2560p laptop
- External Screen DELL (1920X1200 )

At home I'm using only External Screen ( Laptop screen disabled in Display manager) .

When i use minimzez dash . All is OK
When I want to have full screen DASH , effects (for exemple right clic animations) become very slow , fluid but slow .

What's expected: effects should keep the same speed.

Thanks for all your work!

Same here with my Mobility Radeon HD 5430 Series.

Larger is the resolution screen, slower the Compiz effects are ...
