Description madness742 2025-06-19 08:59:35 UTC 
SUMMARY
When trying to reset values to their default, `Map to screen` gets ignored.

STEPS TO REPRODUCE
1. Connect a Wacom tablet (Wacom Intuos, in my case).
2. Under System Settings -> Drawing Tablet -> Display, adjust `Map to screen` to any other value.
3. Hit apply.
4. Click on `Defaults` at the bottom.

OBSERVED RESULT
`Map to screen` does not get changed.

EXPECTED RESULT
`Map to screen` should get changed back to the default value.

SOFTWARE/OS VERSIONS

Comment 1 xanaroth 2025-06-22 21:17:52 UTC 
this feels similar to my Issue, I cant map my Digitizer to my Pendisplay. (Multi screen setup)

Summary:
map the output to a screen gets ignored.

Observed Result:
always active option is the last active screen despite the config file noting the selected screen

Expected Result:
cursor on the tablet only no matter the last active screen.

Also on Fedora 42 and running KDE6.4 but persistent in earlier versions too

kcms/tablet: Refresh the "Map to screen" option during reset

This is because the combo box's current index is decided by a function
call, and isn't a property binding. We have existing infrastructure for
this scenario, it just needs to be repurposed for the Display tab now.
FIXED-IN: 6.4.1
