Weird circle outline on black screen

[vytuzas]

Just recently noticed circle outline in the middle bottom of screen and wondering whether that is something that I might have caused or what. Pretty sure that I never applied pressure on the laptop, since I do not like putting anything on it. Only visible on dark screen and just noticed it when had a long loading time in game. It is less visible to a naked eye, but still kind of worrying whether this is something bad that might evolve. Anyone has any insights?

Its called screen burn-in, i also have a whitish line on the bottom on the screen to the left... i tried using Jscreen fix but it didnt help much, its only visible on solid colors...
