Title:
Restore previous configuration after turning off fractional scaling
does not work
Status in mutter package in Ubuntu:
Fix Released
Status in mutter source package in Focal:
Fix Released
Bug description:
[ Impact ]
It's not possible to restore the application a non-fractional scaling
configuration when fractional scaling was previously enabled and
applied.
[ Test case ]
1. From control center, display panel, enable fractional scaling
2. Set scaling to some fractional value and apply and confirm it.
3. Turn off the fractional scaling switch and apply it
4. Fractional scaling should be reverted to the selected integer scaling.
5. When gnome-shell shows the confirmation dialog, click "Revert Settings"
6. Expect the fractional scaling to be re-enabled and applied as it used to be
[ Regression potential ]
- Configuration can't be applied
- Scaling (fractional or not) is not properly applied in single and
multi-monitor
- Fractional scaling can't be toggled anymore
