The screen recording shows how the volume bar glitches while tring to change the media volume playing on the phone

SUMMARY
***
In the multimedia control section of the kdeconnect app, the volume bar glitches while trying to increase/decrease volume. It is not just a visual glitch, as the volume of the media playing on the connected smartphone also keeps jumping up and down during the duration of the glitch.
***


STEPS TO REPRODUCE
1. Connect the laptop with the smartphone using kdeconnect and provide all necessary permissions on the android device to allow kdeconnect to access complete control over it
2. Play some music on the smartphone. I tried using both spotify and musicolet (3rd party music player)
3. Open the kdeconnect app on the laptop, click on the connected smartphone that is currently playing music and go to the "Multimedia control" section
4. Drag the volume bar.

The volume bar will glitch for a few moments after dragging. It will jump up and down randomly for a few seconds and then settle down. This also glitches the volume of the music playing over at the smartphone for that duration

OBSERVED RESULT
Volume bar shows a visual glitch for some moments, randomly increasing and decreasing. The volume of the music playing also changes randomly during that time

EXPECTED RESULT
Volume bar should remain at the position where the user lifts their cursor
