So you're being upvoted to the top by praising how flawless Wayland works on an OS that runs by default on X11? :))
Aww man, I hope there's a miscommunication somewhere, like you switched PopOS from X11 to Wayland, because otherwise this is HN comedy gold.
I wrote it up at https://shkspr.mobi/blog/2020/05/fix-screen-tearing-on-rotat...
Warning - you'll need to be at least a Level 17 Linux expert to understand the complexity involved.

They said it pretty explicitly
And from my experience, there's distros that work better with X11 which is why they ship with it out of the box instead of Wayland(like Mint, EndeavourOS and Kubuntu), and ones that work better on Wayland out of the box, like Ubuntu and Fedora.
No idea. I'm using Pop OS. So whatever that uses. Gnome is the DE, I think?
