read somewhere that maybe they’re preparing for OLED screens

How does that argument work?

which will be even worse so you don't get that angry after years of bad design, lol

All iPhones since the iPhone X (2017), and not the iPhone SE line, has an OLED display. iPad Pro also has OLED.

There's also been rumours of a new high-end OLED MacBook ("Ultra"?) in the works, possibly this year.

If it is that crucial, they should add a few pixels of margin around the entire desktop, and randomly shift everything around. Doing only corners and not straight edges, and doing it by a fixed per-app amount, seems a bit silly.

is there a reason to downvote this?
