What launcher? I noticed this happening with the internet browser. After i decided to be patient, all is fine. I imagine, as in the PC world, most programs (apps) are not optimized for quad core. Not to mention, ICS is not perfect. It only acts up on me if i don't let a page load before trying to activate another link. I seriously doubt there is anything wrong with the hardware, but I may be wrong. Just my opinion. I love my ASUS. Both of ours work beautifully.
You may have a lemon. No, you shouldn't have to root it to be satisfied and rooting could make things worse if u don't know what your doing. Good luck. Return for another if necessary and get another one.
