So, there's a little issue with Opera. I use MX Linux, XFCE. Since the newest update, Opera asked me to create a new "default" keyring. I created it, so now everytime I boot the OS and start Opera for the first time, it's asking me the keyring. Also, I kind of lost all my saved passwords after this.

Anyway, this is not the main issue. The main issue is when I am in a fullscreened application (KODI), and try and start Opera, while in fullscreen mode, the keyring window blocks any keyboard command, but the window doesn't even show up. Only mouse works, but I can't do anything, I'm forced into shutting the PC down. Any fix for this?
