Updated the issue to follow the format according to the README. Apologies for my ignorance in reading how to submit bugs on this project.

dickmao commented 2 years ago

Sorry, the README wasn't right. I just corrected it in 693373b.

Perhaps you could try again with the new instruction? That will show the websocket traffic where the problem appears to reside.

derekperrin commented 2 years ago

For whatever reason, things seem to be working fine now when I follow those instructions. I'm not sure why they didn't before even when I used -Q and started from scratch. I don't recall doing anything besides rebooting.

I tried to narrow down the problem by disabling sections of my init.el, and I can reproduce it only if I have magit enabled. I'm not sure if this is unique to my system or a problem with magit, but that seems to cause the issue for me. I'm not sure if you want a debug log or to mark this as closed since it's another package that might be causing it.

My OCD finds any excuse to close an issue.
