Description Tech-Tac 2025-07-01 14:38:22 UTC
SUMMARY
More often than not, upon waking up from sleep and getting greeted by the lock screen, the cursor doesn't seem to update when hovering over the password box and stays as the default arrow cursor all of the time.

This issue (probably) extends to the cursor sometimes not even showing up, you can still move it around and hover stuff but the cursor is not visible.

STEPS TO REPRODUCE
1. Sleep
2. Wake
3. Cursor

OBSERVED RESULT
Cursor doesn't show the I-beam shape when hovering the password entry field, it is sometimes not visible.

EXPECTED RESULT
Should behave correctly and not disappear.

SOFTWARE/OS VERSIONS
Linux: Arch
KDE Plasma Version: 6.4.1
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.1

Can you confirm if disabling the screenlocker still results in a frozen screen?

If not please reopen this.

This is not the same bug, the lock screen is perfectly functional, it's a cursor rendering thing.

Also I have a single monitor and no Nvidia GPU.

Does the issue ever reproduce in a new clean user account on the same machine with no customizations applied to it?
Comment 4 Tech-Tac 2025-08-17 14:52:18 UTC
Yes, I can reproduce on a newly created user account.
Comment 5 Tech-Tac 2025-08-18 16:06:45 UTC
I've discovered a similar (if not the same) bug when switching TTYs, where the cursor doesn't update until it crosses over windows.
