Sleep monitor bug on AMD Discrete GPU Plasma 6.4.x

Help

Dear All,

I have been having issues on monitor sleep bug, on 2 machines with AMD discrete GPUs, the monitor does go to sleep, and after a very little time, it wakes on its own, like some ghost, waking up the system.

Never had this issue on plasma 6.3.x, but is the first thing I have noticed on this new version is this bug, also browsers often closing and some random windows.

The rest everything works properly.

Having the same issue on Arch, with dedicated AMD GPU.

If you use headphones or have speakers on, when locking screen and press esc for monitor shutdown, you notice after a few time, a sound similar of a usb stick connecting to a usb port, I guess something triggers an event which makes KDE Plasma output that sound, and that awakes the monitor.
