Well, here I am again with yet another irritating problem with my almost brand new 27 inc iMac. I was able to capture it with my camera when I was booted into Windows 7. This is what it looked like: http://data.fuskbugg.se/skalman02/4e4575ce5cf8f_IMG_8473.JPG The only other times I've noticed it is when I've been working in Logic 9. It's not that much of a deal since it only happens sometimes, and usually goes away pretty fast. It also goes away instantly when moving a window over it (presumably because it forces the pixels to change). As far as I can see, the "dots" doesn't cover the entire screen, just a small portion of it. It's pretty hard to spot in the picture, so I've highlighted it. It may not seem that major, but it's much easier to spot from a normal viewing distance. Any ideas?
