Cannot reproduce on Wayland or X11. Can you attach screenshots of your settings for the "On AC Power" and "On Battery" tabs?

Thanks. Does the issue go away if you check the checkbox for "Screen brightness" on the "On AC Power" and "On Battery" tabs?

Hi Nate With the power options enabled for the screen brightness it still tries to dim but then comes back up to the correct brightness. There is a flash of the dimmed screen of about 1 second.
That seems relevant. Seems like there's some default action that's getting executed that shouldn't.
I have the same issue: The screen brightness is dimmed when the power plug is put in for the first time. ADDITIONAL INFORMATION When I plug in the power cord on the lock screen the brightness is dimmed and I can not use the keyboard buttons to brighten the screen up. This makes using the laptop in a bright room practically impossible since I can't even see weather I'm typing the password or not.

Is anyone still having this problem on Plasma 6.3.2 or later?
