Whilst watching a flash video in Chromium this evening, I scrolled down the web page and noticed the tearing even when I had "EXAPixmaps" "off". The tearing was not as severe, but nonetheless occurred. As a quick test I tried setting the VGA-0 Display to 1680x1050 (DVI-0 still at 1920x1080) and it was fine. Using just DVI-0 standalone @1920x1080 also had tearing. Thanks -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
