Lock screen asks for password twice
Using GNOME 3.30.2 on openSUSE Tumbleweed.
The lock screen shows up twice to ask for my password. The first time is normal, the second time the top bar shows up as it would if I were normally logged in, but the screen stays on the password input field. However, I can't enter anything in this field unless I first click Cancel and then try again. After that I'm fully logged in as I should be.
I think it starts happening when I connect a second monitor via HDMI (but not 100% of the time), and it stays that way even if I remove the second monitor again. The only way out is by restarting GNOME Shell (or a reboot), which is why I'm posting the issue here and not on the gdm tracker. I can't consistently reproduce the bug, but let me know if you need any further information.
