Description Till Schäfer 2018-12-20 14:27:33 UTC

SUMMARY
When the checkbox "exclude range from anti-aliasing" is toggled, it is not recognized as change by the fonts kcm. This is observable by the following two indicators: 
- The apply button does not get enabled. 
- quitting the font kcm does not raise apply/discard/abort dialog


SOFTWARE/OS VERSION:
Linux: Gentoo Linux
KDE Plasma Version: 5.14.4
KDE Frameworks Version: 5.53.0
Qt Version: 5.11.3

Comment 1 Till Schäfer 2018-12-20 14:37:53 UTC

there are more oddities, when clicking the button defaults in the fonts kvm, change to another kcm and discard the changes, and then switching back to the fonts kcm, the option "exclude range from anti-aliasing" is always enabled with 0 to 0 exclude range.
