A couple of months ago I discovered that I have broken pixel on my laptop screen:
The weirdness of it is that it isn't a broken pixel at all, because as you can see I'm able to screenshot it.
The first time it appeared, I just rebooted my laptop a couple of times and it was gone, but this time it won't leave me even after 10 reboots and "screen fixer" for stuck pixels.
I can hover the mouse over it, and I can record it on video, but when I open exclusive fullscreen applications like games (CS:GO in my exact case), it doesn't show up.
I did a virus scan and I don't have any pirated software installed. No new software/updates were installed recently.
Important note: it appeared in the same place as the previous time, but when I change the resolution of the screen it does move a bit.
