Screen dying already?

[rocket2nfinity]

I have had the Manjaro CE since November and have been using it as a daily driver pretty much the whole time I've had it. Unfortunately, my screen has recently been getting these deformations(?) around the edges, see photos:





They've suddenly appeared one day, starting with the bar of rectangles on the top and spread to the sides in the span of around a week, although it seems like it's stopped now. It's only visible when I shine a light on the screen, i.e. can't be seen in the dark with just the backlight shining. It doesn't look like it's damage to the screen protector or the glass, the artifacts look like they're below the glass. Is the screen permanently damaged? What could have been the cause of this? Damage by heat? Water (air moisture)? Pressure? If I replace the screen, what can I do to avoid this in the future?

That is unfortunately the screen separating, likely due to pressure. The glues are usually alcohol based solvents so it's likely not water. You could continue to use it, but it will need to be replaced at some point.
