SUMMARY
Applications change displays after resuming from sleep. 

I'm running 2 monitors on F36.  I work on my main monitor.  I run Firefox and Okular on my side monitor for viewing media and documents while I am working. 

Everything works fine until the computer goes into sleep mode.   After it does, the applications that were in the side monitor are now full screen on the main monitor.  Every time my computer comes out of sleep I have to move all the applications that were in the side monitor from the main display to the side display.    It is a real pain in the butt. 

STEPS TO REPRODUCE
1.  Start a KDE session.   
2. Open several apps and place them in the side monitor.
3. Let the computer go to sleep. 
4. Bring the computer out of sleep. 

OBSERVED RESULT
The applications that were in the side monitor are now in the main monitor.  Usually full screen or extremely large, ie they kept their relative size from the small side display.  

EXPECTED RESULT
Applications should be in the monitor/display that they were in before the sleep event. 

For whatever reason it won't do this if I select Start -> Sleep and then bring it back out of sleep.   Must be time related or something.  If I walk away from my computer for 10 minutes or so it does it.   

It does this on multiple machines, with Nvidia and AMD Radeon video cards.

I updated to Fedora 37 with KDE 5.25.5.  No change.    Fedora should ship KDE 5.26 this week with the official F37 release.
