SUMMARY

When hitting the caps lock key on a Logitech MX keys keyboard in a Plasma Wayland session, the caps lock indicator light on the keyboard often does not toggle state and thus differs from the effective caps lock state of the session.
The caps lock indicator on the built-in keyboard of the laptop accurately shows the session caps lock state.

In a Plasma X11 session, both the built-in and MX Keys caps lock toggle and display the session caps lock state correctly.
