What happened?

I upgraded from Synergy to Barrier, and was initially pleased, but quickly found that sometimes the mouse would jump around on the client screens rather than moving smoothly - it seemed like it would quickly jump back and forth between one fixed location and the actual area it was moving through, while moving at half or less of real time. This made barrier effectively unusable. Restarting would fix it for a few seconds, but it would quickly break again.

It turns out I unfortunately still had an old Synergy service running on a Windows VM. It was generating various errors in the logs about insecure/failed connections, but I figured those were harmless, and I couldn't track down where they were coming from. However, once I turned off that service, those errors and the glitchy mouse movement went away.

I don't know where this is coming from, but it seems like a clear bug if unknown connections can completely break this.
