Wow I'm not alone! Was going to contact Evernote but found this first. I installed v10.4.4 last month after not upgrading for a long time (2016 Macbook with OS Catalina). I wanted Dark Mode in Evernote because I take notes on sales calls for my job and 1) need to type very fast 2) don't want a bright screen reflecting in my glasses. In the new version, typing is so unresponsive. Especially if I make a typo and work to fix it quickly. It's def slowing my work down.
To me, I notice the lag most when I see the notice that Evernote is "Saving..." on the bottom right of the screen. It's like saving every 2 seconds is messing up the typing.
Thanks to everyone joining in about this and I hope it is fixed soon. I may downgrade to an older version in the meantime.
