Hello. I have recently bought an Acer Aspire V3-574, and a few days ago I noticed that when I use certain programs (like, for example, Adobe Acrobat Reader DC or Firefox), a short line of pixels on the top left of the screen changes color. This line appears and disappears at random when I move the mouse, and it's always on the same spot.

When I try to take screeshots, the line doesn't appear on them. I am starting to think that maybe certain color combinations being displayed on the screen trigger it, because when I put a screenshot of Adobe Reader Acrobat with a PDF open on fullscreen, the line started appearing and dissapearing as well.
I've also connected the laptop to a TV to check if it was just the laptop's monitor, but the line appeared on that screen too.
It would appear that the line is more likely to appear if text is being shown in the screen, but I'm not completely sure.
I don't know if it helps, but sometimes I was able to move the cursor to the line, and it seems that the cursor goes over it (it can be seen on the second picture).
I've also tried changing the resolution a bit, and it seems the line still appears. All the laptop's drivers are up-to-date.
Laptop spec's:
*Windows 10 Home Single Language 64-bit Version 1511
*Intel Core i5 5200u Dual-core 2.20 ghz
*Intel HD 5500
*8 GB RAM
I would like to know wether this is a hardware or software issue. This isn't really that annoying, as it seems to appear only under certain specific conditions, but I'm worried about this becoming worse later on, so any help or information is appreciated.
Thanks in advance.
