SUMMARY

STEPS TO REPRODUCE
1.  Plug second screen, make it not a replica of primary screen
2.  Run qonk game, switch to full screen, then back to windowed
3.  Go to system settings > Display and monitors

OBSERVED RESULT

The second screen is now a replica of the primary, but in the second screen's config, "Replica of" is set to "None". Setting it to primary screen then back to "None" doesn't change what's on the second screen.

EXPECTED RESULT

"Replica of" should be the primary screen. Setting it to "None" stops mirroring.

The following command stops the mirroring:

$ xrandr --output $SECOND --auto --right-of $PRIMARY
