SUMMARY This is a feature request regarding application consistency with KDE Plasma STEPS TO REPRODUCE 1. Install the app from the ubuntu repository or flathub (version 0.9.3) 2. Look at the default UI on first launch. (IMAGE: https://haruna.kde.org/assets/img/haruna-breeze-dark.png) OBSERVED RESULT 1. The video progress bar has sharp corners. 2. Volume bar to adjust application volume has sharp corners. EXPECTED RESULT The title bar with minimize, maximize and close options in KDE Plasma 5.25 (or above) has slightly rounded corners for most applications including Haruna player [See: https://haruna.kde.org/assets/img/haruna-breeze-light.png] If UI elements of this application use rounded corners with similar curvature, the application will look more consistent and thus more native application to KDE Plasma. This will also be beneficial on other desktop environments like GNOME 43. Thus, desired result is as follows: 1. The video progress bar has rounded corners. 2. Volume bar to adjust application volume has rounded corners. SOFTWARE/OS VERSIONS Linux OS: Kubuntu 22.10 (available in About System) KDE Plasma Version: 5.25 KDE Frameworks Version: 5.98 Qt Version: 5.15.6
