How do I trigger this to get run? Restarting plasmashell or opening the Style KCM didn't seem to do it.

To run the update script, just apply the patch and rebuild plasma-desktop.

To confirm it has run in .config/kconf_updaterc at the end you will see

[style_widgetstyle_default_breeze.upd]
done=StyleWidgetStyleDefaultBreeze,StyleRemoveGeneralWidgetStyle

And in .config/kdeglobals should have updated widgetStyle entry in group KDE

This fix the issue for Breeze theme, but according to bug description (https://bugs.kde.org/show_bug.cgi?id=417515) some configuration file may also have oxygen instead of Oxygen and maybe the case for fusion and window them style.

Did that.

[style_widgetstyle_default_breeze.upd]

I see the following:

[style_widgetstyle_default_breeze.upd]
ctime=1582046255
done=StyleWidgetStyleDefaultBreeze
mtime=1582046231

And in .config/kdeglobals should have updated widgetStyle entry in group KDE

I still see widgetStyle=breeze (not capitalized) in the file. :(

Weird, I've tested again, and works like expected on my machine.

Is it the widgetStyle entry from KDE group ?

I have also an entry named widgetStyle in group General but we are not interested in that one.

Works : replace widgetStyle in group KDE and selects the application style in systemsettings; Does not edit widgetStyle in group General

Thanks for the confirmation.

+1 on fixing whatever lowercased the value in the first place. Comment by @bport

Fixed by D27407

@ngraham do you confirm it is not working ?

I think I did--for me at least. But I won't block this because I'm not sure if my kdesrc-build-built setup is capable of testing kconfig patches adequately.
