Breeze's icon theme replaces app icons, like those in the LibreOffice suite, to match its style. However, switching to a non-Breeze theme doesn't fully revert these changes. It would be helpful if users could choose whether to use Breeze icons or apps' original ones.
Ideally, the Icons menu should include a "None" option or toggle. This would keep KDE apps using their default icons while restoring original icons for apps like the LibreOffice suite.
