Is anyone else having any issues with CS8 kernel-4.18.0-358.el8.x86_64?

The symptom I'm seeing is not getting the kde screen locker password prompt to show so I can't unlock my screen.

I have already rolled back the recent qt5 and xorg updates.

Booting into the previous kernel - 4.18.0-348.7.1.el8_5.x86_64 fixes it.

No idea what might actually be causing it.
