hello everyone i ve noticed in the latest nightly build that i cannot enable full page accelerated drawing in debag menu ,also scrool on some webpage is choppy and never as smooth as in chrome! i ve disabled all plugins and i only use two extension(last pass and helvetica all the world)
Choppy scrool is the same in safari stable...and uses more cpu than other browser.
i ve also tried deleting safary folder in library and deleted prefs!
sorry for my bad english thanks everyone

it happens on all websites (eg macupdate.com) today i made some more experiments
i used gfcardstatus and i solved the problem (well so so) :
choppy scrool happens with intel card
smooth scrool with nividia
so i assume is a driver problem
anyway i tested this with a 2010 macbook pro (core i 5 + intel hd / nividia 330)

os: lion 10.7.2
even tried 10.7.3 no difference
best regards everyone and sorry for my bad english!

yeah i used than app
another experiment
scrool on my mac mini 2011 with intel hd3000 is as smooth as with geforce 330
so i m quite sure it s a bad intel hd(not 3000) driver the problem!
maybe it s not powerful enough??
