randomly stops working after a while

[dnut]

Sometimes I notice all the clipboards break after the service has been working fine for hours or days. Not only is it not synced but I can't even copy and paste within a single display. Restarting the service always fixes it.

Something is getting into a bad state, but I'm not sure what. I have a suspicion there are some issues with some displays starting and stopping while the service is running but I don't see how that fully explains it. I need to add some extensive debug logging (probably do #10 at the same time) and check out the logs whenever this happens.

today i saw it stop syncing across displays but worked fine within one display, systemd service says it's running but the last log was right after it started over four hours ago
