Since the last X11 security update (not sure if related), my "Battery and Brightness" menu in KDE becomes completely out of sync with the current display and keyboard brightness. If I change the keyboard or display brightness, it does change in reality but the menu stays stuck at the login values. I can still use the brightness slider and it does apply the changes, but will fall out of sync when I use the function keys. Another side effect is that on resume from sleep, the screen brightness is set back to the value indicated by this menu.
The issue does not occur if I login while running on Battery power, or if I kill plasmashell then start it from the command line (on AC).
My system has hybrid AMD GPUs (iGPU+dGPU), I run most Debian stable packages except for the kernel (for hardware support) and a few other things.
I also have "asusctl" and "supergfxctl" installed.
Operating System: Debian GNU/Linux 12
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.11.5+bpo-amd64 (64-bit)
Graphics Platform: X11
