This might just be a gnome-control-center GUI bug. When the fractional
scaling switch changes unexpectedly do you also see a change in the real
setting?
gsettings get org.gnome.mutter experimental-features

Title:
Display settings don't persist across reboot / sleep
Status in gnome-control-center package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
Incomplete
Bug description:
My setup:
Dell XPS 13 7390 2-in-1, internal display (3840x2400)
First external monitor: Dell 24" running at 2560x1440 connected via
USB-C/Thunderbolt
Second external monitor: same, connected to the first monitor via DP
Scale of the internal display set to 200%, fractional scaling on
Scale of the external displays set to 100%, fractional scaling on
What I expect:
Settings persist across reboot / sleep / resume.
What I observe:
Settings for external monitors are back to 200% scale, fractional
scaling off.
Looks like there's a problem detecting the external
monitors/resolutions in time.
