SUMMARY When having 100% volume, while going down, it actually starts decrementing from 94%, instead of 95% (assuming a 5% increment/decrement is used), however, starting from 0%, it uses the correct value (that means 5, 10, 15, etc.) STEPS TO REPRODUCE 1. Set volume to 100% 2. Start lowering the volume 3. See the current level of volume OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Manjaro (with Wayland) (available in About System) KDE Plasma Version: 5.21.4 KDE Frameworks Version: 5.81.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION This seems to be a Wayland issue, as on X11 it is working correctly.
It's an X11 issue too. Fixed in Plasma 5.21.5 *** This bug has been marked as a duplicate of bug 434769 ***
