EXPECTED RESULT

GTK application respects theme set in plasma settings

ADDITIONAL INFORMATION
Comment 1 Nicolas Fella 2024-03-07 10:56:55 UTC 
Is kde-gtk-config and xdg-desktop-portal-gtk installed?
Comment 2 Nate Graham 2024-03-07 17:17:44 UTC 
Which apps specifically?
Comment 3 daf 2024-03-07 22:57:23 UTC 
@Nicolas Fella

yes on kde-gtk-config
no on xdg-desktop-portal-gtk

Wouldn't xdg-desktop-portal-gtk only be needed in non plasma desktops?

@Nate Graham

Confirmed on Mozilla Firefox 123.0.1 and Input Remapper 2.0.1
Comment 4 daf 2024-03-07 23:23:38 UTC 
installing xdg-desktop-portal-gtk seems to have fixed the theme miss-match, apologies for the false report
