Macbook Air has a dead pixel when waking up, then fills in later

[mysticmanix]

Something I've noticed over the past month or two for my Macbook Air 15 I bought in August, I thought it was some software glitch, but now I think it might be hardware: everytime I wake my Macbook from sleep, there will be a dead pixel in the very center of the screen, then it fills in after 10 to 15 seconds. Even if I use it for an hour or two, it doesn't seem to go dead again but happens every single time waking from sleep. At first I thought this was software, but after changing wallpapers through 4-5 different ones, and 2-3 macos updates, it still happens.

Anyone experience this before?

First time seeing someone saying their screen has a what I call degraded pixel. I never saw this before on any Mac I used.

Try booting into recovery mode and seeing whether the same issue persists there.

There are some very strange display bugs in MacOS, for example I've had what I thought to be burn-in, where I could faintly see the menu bar when running a full-screen game. However, that was fixed with a reboot!

Same. My brain has more than a few dead pixels that don't fill in until after I've been awake for a bit.
