Is this mod fixes cursor locking?

I'm having issue running GNOME with Wayland - cursor never locks it's position in the center of the screen. So when I reopen inventories my mouse cursor stays at the position it was before closing it. Also in windowed version it leaves the window when I move my mouse

Not yet, but seems like this is getting fixed in upstream #2772

This fix was cherry-picked in newer lwjgl so 26.1 has fixed cursor locking.
