recently, I have been fighting with the typing lag in obsidian. I looked into the activity monitor, and found two thread constantly took up over 100% cpu time, one is obsidian helper (renderer), the other is window server.
I tried many things, like turn on the safe mode, close some other apps. Yesterday, I just realized that new edit mode that just released might be the reason.
Indeed, when I restored to the older version of editor, the typing lag was gone.
However the new edit mode is very straightforward and useful, I hope this bug will be fixed soon.
Thanks guys, obsidian is great!
