i noticed that my computer stutter/lag/hang abit when it changes wallpaper or wallpaper + windows theme color
just for a sec

laptop acer aspire 4755g

what i noticed is that IF its just the intel HD 3000 and didn't installed the dedicated Nvidia GPU GT540m, it work just fine
but if i install the GT540m regardless of the driver version its still the same

if there any ways to solve this?

its working fine on games and such just that weird stutter

when it was on windows 7 it wasn't like that
