Screen scales to grandma very unfriendly mode

Bug Description

When fractional scaling is active and set to 125% (I only tested this with 125%) and then the switch for fractional scaling is deactivated again, the screen scales well beyond the standard (and selected) 100%. Feels like 50% or less. This issue is removed when rebooting.

While the effect seems duplicate of #1875285, I think this is more related to bug #1876894, and so marking duplicated of that.

However, to understand properly this the `xrandr` command should include the `--verbose` option, otherwise it's not too easy to get what's going on.

Actually no, ignore the point on duplicate (even this may be fixed by the changes included for that fix), but still would need better output.
