Reverting to both 100% and 200% works fine, without issues. g-c-c now
requires a further "apply" to turn it off, and mutter reacts properly
when setting it back to both 200% and 100%.

Bug description:
* Impact
Scaling is not reverted properly (appears shrunk) when disabling
fractional scaling
* Test Case
Do this in an Ubuntu/Xorg session:
0. Be on a "clean" system wrt. fractional scaling, i.e. disabled & scaling at
100%
1. Open gnome-control-center → displays
2. Turn on fractional scaling
3. Select 125%
4. Press apply (the scaling should correctly change now)
5. Turn off fractional scaling by changing the toggle
Now everything is shrunk - it's not been returned to 100% properly.
See the attached screenshot where the text is tiny instead of regular
100% size. If you do this instead of step 5:
5. Select 100% scaling
7. Press apply
8. Turn off fractional scaling by changing the toggle
Then everything returns to the normal size.
Repeat the same selecting 200% at 5., (or 100% if 200% was your
default) and ensure it's applied.
I'm on nvidia(-440), but Séb said that he saw this on his Intel
machine too.
* Regression potential
Verify that scaling changes are correctly applied on different setup
