I am with the Macbook Pro 13 Mid-2010 2.4Ghz; nVidia 320M; 8GB DDR3 Ram; and OWC 120GB Mercury SSD. Recently, I realised that there are some yellow pixelating problem whilst surfing the internet with both Chrome and Safari (See Attached). Weird thing is, whenever that happens, just a scroll down or up will eliminate this yellow pixelating problem and everything returns to normal. No jams no nothing, just this slight discolouration. It does not impede me from doing anything but I just find it weird unto why this will happen. Anybody faces the same issue as mine?
