Square pattern/sub-pixels on MacBook display.
I can see see a compact (sub-pixel?) pattern on my MacBook display. They're like small fuzzy squares which only seem visible when close up, or at certain angles. Note that it's impossible to photograph. It's not exactly intrusive, but it's certainly kinda distracting now that I've noticed it on solid light colours.
Is this normal? At least if I know it is, it'll give me some peace of mind.
MacBook Pro (Retina, 15-inch, Mid 2015), OS X Yosemite (10.10.3)
