It's not the first time I've had this problem, but it's really annoying, it's making it almost impossible for me to use joplin, I'm guessing it might have something to do with me having two monitors, but I'm not sure what the problem is
I disconnected the monitor and restarted joplin and everything is back to normal now, but in general I use the external monitor as my main screen and start joplin on boot
I use Joplin on Windows with two monitors of different resolutions and I can't say I've ever seen anything like that. Don't suppose the dev tools console log shows anything weird rather than the main log?
