Created attachment 126168 [details] screenshot STEPS TO REPRODUCE 1. set global theme to Breeze 2. set Plasma style to Breeze dark 3. set task switcher to Large Icons 4. open KAudioCreator and press alt+tab OBSERVED RESULT as we can see in the attached screenshot, task switcher shows low resolution icon of KAudioCreator EXPECTED RESULT crisp KAudioCreator icon SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.18.1 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1
This isn't a Breeze icon issue; KAudioCreator seems to be providing its own low-resolution oxygen-style icon. It also seems to be unmaintained. :/
on https://apps.kde.org/kaudiocreator/ we can read: 'This app is unmaintained and no longer released by the KDE community.'
