X11 can't do different hz on different screens. If you have a dual screen setup where one screen is 165 hz and the other is 60 you're SOL.

Works fine for me with 144/120 with the second as 60.
What's happening is you are running both screens at 144/120 and your 60 is gonna have vsync and screen tearing issues.
What vsync issues?

Couldn't you stop tearing with a couple lines of code? Don't swap out buffers mid-frame, very simple.

The simple solution doesn't make 144+60 look super smooth, but 120+60 should be almost perfect.

How does wayland handle the hypothetical problem of playing a 24 fps movie split across a 48hz and 60hz display?

(Hint: It’s not possible to solve correctly.)

X11 can't fix climate change.
You joke, but the wayland protocol leaves this up to the compositor. Nothing in the protocol prevents your desktop environment from doing this.
I heard the desktop environmentalists are working on such a project.
