I was watching a movie today, and noticed a dot on the screen. I scrubbed it hardcore, and it didn't go away. I freaked out because it might be a stuck pixel. After close observation, there are tiny extensions (probably its feet) around the 1-2 pixel size bug. I've taken a screen capture, but the bug is not displayed on it. Is it actually a bug? Should I take the glass off and exterminate the thing?
