Well I will let the pictures do the talking. The first picture is my desktop. I currently have my wallpaper set up to change every 10 min. There are 3 pictures that rotate and as you see in the first picture, they are merging together... The second picture just shows some weird 5h*t. This happens almost every where. It happens a lot in YouTube. I have a MacBook pro i7 (2010). It's only 1 month old and this has been happening for like 2 weeks but it does not happen everyday. More like every 2-3 days. I have to restart my computer to fix. Should I be concerned?
