Original GitHub issue: https://github.com/feschber/lan-mouse/issues/245

On windows I get this error on the terminal whenever my cursor of sway hits the border.

The windows device is LenovoSlim7x running Windows11 on Snapdragon XElite ARM Processor.

WARN lan_mouse::server::emulation_task] network error: network error: A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself. (os error 10040)

could you confirm that you are running the same version on both devices?

I'm getting the same error, trying to connect from Hyprland on Arch Linux to a Windows 11 laptop. I actually just opened https://github.com/feschber/lan-mouse/issues/248 to track that, but it may be the same issue?

@NeveIsa are you by any chance running Arch, btw? I ask since I just figured out that Arch still has lan-mouse 0.9.1 in the official repo, while I was using 0.10 on my Windows laptop. I just downgraded to 0.9.1 on Windows and now things are working.

I've had this issue when using the v0.10.0 Windows binary (I suspect the actual build is not v0.10.0 but idk why). If you're downloading the pre-built windows binary, try the development build.

I can second this, the v0.10.0 Windows binary yields the error in the original post whereas the development build works.
