Public bug reported:
[ Impact ]
If selecting another integer scaling after disabling fractional scaling
[ Test case ]
When running Ubuntu session under X11, in gnome-control-center, display panel:
- Ensure 100% scaling is selected and applied
- Enable fractional scaling
- Select 200% scaling (or bigger integer scaling)
- Green "Apply" button should be visible and clickable
- Deactivate fractional scaling
- Green "Apply" button stays and fractional scaling isn't disabled until
applied
Repeat with inverted scaling orders (applying 200% and then selecting
100%)
Currently, once another integer value is selected, we just deselect the
user choice and restore the previous one, deactivating the fractional
scaling promtply.
[ Regression potential ]
- Displays are wrongly disposed and configured when fractional scaling is
enabled
- Configurations are not applicable.
