Just had the strangest issue with Joplin, not really looking for any help as it seems to be an upstream problem, but wondering has anyone saw anything like this.
I'm on Linux Mint, I had both Joplin Dev running, syncing to Nextcloud, and regular Joplin too. Tried to install the Rich Markdown plugin, was told to restart which I did. After restart the window opened to ~3/4 of the screen (was maximized before) and both mouse and keyboard almost stopped working, the cursor was moving but clicks were not registering.
I managed to switch to tty and kill the process and it brought everything back to normal.
