Same here,
### System
* Fedora 44 KDE
* Wayland
* Issue started after upgrading to Fedora 44
### Problem
After the laptop has been **locked for some time** (especially after suspend),
the **first password attempt on the KDE lock screen always fails**, even though
I'm certain the password is correct.
The second attempt succeeds with the exact same password.
### Things I've noticed
* The problem **only happens on the KDE lock screen**.
* It **does not happen on the SDDM login screen** after a reboot.
* If I lock and immediately unlock the screen, authentication works on the
first try.
* The issue appears only after the screen has been locked for a while or after
waking from suspend.
* The most interesting observation is that if I **type my password, click the
"show password" (eye) button, verify it is correct, and then press Enter**, it
authenticates successfully on the first attempt every time.
### Logs
The journal shows the first authentication being rejected by PAM:
```
kscreenlocker_greet: pam_unix(kde:auth): authentication failure
unix_chkpwd: password check failed for user
```
A few seconds later, entering the same password succeeds.
The suspend/resume sequence itself appears clean, with no kernel, GPU, or SDDM
errors.
### What I've tried
* Verified the password is correct.
* Reproduced the issue multiple times.
* Confirmed it only affects the lock screen.
* Collected `journalctl` logs around the failed authentication.
