Created attachment 168214 [details] Observed: Disk usage indicator not following Fusion style SUMMARY The disk usage indicator in the status bar only seems to be properly styled when using the Breeze application style. With other styles, even with those that ship with KDE (Fusion and MS Windows 9x), it looks Oxygen-ish instead of following the selected style. STEPS TO REPRODUCE 1. Select and apply the Fusion Application Style in KDE's System Settings 2. Open Dolphin 3. Observe the disk usage indicator in the status bar OBSERVED RESULT Disk usage indicator is styled similar to the Oxygen style (see attachment). EXPECTED RESULT Disk usage indicator should be styled in the Fusion style. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.3 Note: This is a long-standing bug. ADDITIONAL INFORMATION I've found this possibly related bug: https://bugs.kde.org/show_bug.cgi?id=166650 , which was solved by making the disk usage indicator use KCapacityBar. If I understand correctly, KCapacityBar is not a standard Qt widget and Breeze seems to be the only Qt style that styles KCapacityBar.
