Description Chris Russell 2021-06-29 18:03:28 UTC 
SUMMARY
I have 3 x 4K monitors connected to a single graphics card that I have positioned normally for a large wrap-around desktop. 
If I install the old BlockOut II game (available in Software Center) and run that app in full-screen mode, it resets the screen layout so that all three desktops are on top of each other (i.e. if you go to System Settings | Hardware | Display and Monitors you'll see _one_ display monitor (w/the other two apparently missing). Dragging the one visible monitor reveals the 2nd, and so on... It would not seem that the app should be able to persistently alter these settings?

STEPS TO REPRODUCE
1. Install Blockout II
2. Launch game in full-screen mode
3. Exit the game

OBSERVED RESULT
Multi-monitor screen layout data is reset persistently requiring that I go back into Display and Monitor and re-arrange the display monitors. What's not great about this is that it's not immediately obvious what happened or how to fix it. 

EXPECTED RESULT
No persistent changes to multi-monitor screen layout settings (i.e. settings restored) on exit from app.
