Thanks!

That's a Hyprland regression (something with the pointer constraints by the looks of things). Please report there and link the issue here. A crash should be easy to fix.

Thanks for looking , I have made an issue at the Hyprland repo which can be tracked here

I only see this behavior when using the stable version of Hyprland. There are no crashes when using the git version, but on git version I can't move the cursor if the other computer's location is set to [left] or [top], only [bottom] and [right] works. That's clearly a regression cause on hyprland 0.39.1 it works great

This solution tested and works

@Clutchnp has this been fixed upstream because you closed the issue?

[Clutchnp]

Oh mb i closed this by mistake

Temporary workaround. I could upstream this but I'd rather get it fixed in Hyprland ...

You can use the patched hyprland-fix branch for now

[interbattles]

whats the difference between this and https://github.com/drendog/Hyprland/tree/fix/cursor-min-padding nevermind, but are we planning for that to be fixed on hyprland or merging this branch at some point

[Clutchnp]

Waiting for #6027 to be merged, until then you can hyprland-fix-branch of lan-mouse
