Problems with screen painting in safari?
Ever since upgrading to Mountain Lion, I have problems in Safari on a regular basis with the screen not updating/refreshing/repainting properly. It's seem particularly bad when typing in a text box on a web page, for example GMail when composing an email or when using Facebook website. When typing, characters are captured but do not show on screen (they are there...I can shift+backspace and then copy the characters).
Anyone else seen this problem or have suggestions? Using a 15" Macbook Pro late 2011 model.
Thanks!
MacBook Pro, OS X Mountain Lion (10.8.2)
