Deciding how to lay out the desktop isn't driver-related, reassigning.
Comment 4 Ray Strode [halfline] 2017-07-27 16:29:31 UTC 
looks like cc-display-panel.c has a function realign_outputs_after_resolution_change that needs to get called when a display is marked inactive (and it maybe needs to be slightly modified, too).

moving to control-center
Comment 6 Tomas Hudziec 2018-08-31 14:06:53 UTC 
Not reproducible in RHEL 7.6. After turning off the middle monitor via display settings it makes gap between side diplays, but user must drag one to another to apply changes.
