I have absolutely no idea but like I said before it doesn't seem like a coincidence as in the same randomness the a screen problem is happening but with less of an effect as on Arch. Try running EndeavourOS or Arco on your laptop as well, if the same thing happens as with Arch i.c.w the very similar problem happening on Windows it only makes me think it's a hardware problem. After you have done that and you still get the same result I would send it for checkout to the place where you bought it from. I have no more ideas for you, I'll be looking forward to your updates.Another behavior that I noticed is the fans' noise. On Windows the fans' noise is way louder than they were under Linux. When thinking about it I remember that I use the thermald daemon to control the temperature. Could this have something to do with the issue?
