Hi there.
I’ve been looking around for solutions and couldn’t quite find someone with the same situation as I have.
I am running KDE Plasma in a dual monitor setup.
Most of the time it works fine, the problem is that my secondary monitor takes all the windows upon waking up from sleep,/hibernation, at boot or even after both displays timeout.
When powering up, my primary display shows the login screen (for a brief moment), and because my secondary screen is slower to power up, as soon as it starts displaying, everything switches to it.
After each login all of my windows that have been on my primary monitor switch to the secondary one.

The HDMI-0 Connection is my secondary display. And KDE successfully retains that my DP-0 Connection is my primary, but on every login it will still open all of my windows on the secondary display.
Any suggestions or help regarding this matter will be greatly appreciated
