Screenrecording of plasma-pa's device tab

SUMMARY


STEPS TO REPRODUCE
1. Pair and connect your Bluetooth headset
2. Change the volume in the device tab by dragging the slider

OBSERVED RESULT

The slider is indeed dragged to the destined position but while dragging jumps back to the position of the current audio volume state and forth again to the current dragging position.
When released it jumps to the current audio volume state position and then moves and updates by itself until the final setting is reached.


EXPECTED RESULT

The volume slider does not jump back and forth while dragging. Once released it may move by itself. However, it'd be even better if the sound volume would be applied immediately without intermediate steps.
