Steps to reproduce:

• Turn on Librem 15v3 and log into GNOME Wayland desktop
• Wait for lock screen (screen also goes black)
• Hit any key to bring up unlock prompt
• Enter correct passphrase

What should happen:

• Desktop restored

What happens instead:

• Correct passphrase rejected
• Enter correct passphrase again
• Desktop restored

Notes:

• Intermittent issue that occurs 95% of the time. It feels like leaving the machine longer makes it more likely to happen. Typically doesn't happen if unlock attempt made immediately after screen locks/blacks out.
• Typed passphrase carefully the first time to ensure not caused by a typo.
• I have non-standard settings for: autologin flag, login keyring, lock timer, black screen timer, possibly other related settings. Happy to provide them and/or put time into reverting them for testing purposes, if required.
