I can reproduce this, but it's going to be difficult to fix with the GTK version of the indicators. Leaving it open for tracking, but I expect the QML version won't have this issue as the event handling is very different.

If you move the mouse horizontally (perhaps beyond a small "tolerance" of a few pixels) you won't reproduce the issue - drag downwards, untill outside the volume widget. Do not release the mouse button yet - now move horizontally (still keeping the mouse button pressed), for example to the left. Now the volume slider doesn't move, which is expected (well actually it should keep following mouse movements, but this is a minor issue and it can be considered ok, in a kind of incomplete imitation of the drag-too-far-cancels-interaction way certain UI elements work) - move the mouse cursor vertically upwards, so as to go back into the slider area. Expected: the slider handle should now jump to the position of the mouse cursor and follow mouse movements, as it did at the beginning Observed: the slider handle jumps to some apparently random position which is somewhere midway between where it was and the mouse cursor. As you move the mouse cursor to the left or to the right, the slider handle moves too in the same direction, but much "slower", that is, the slider handle movements reproduce mouse cursor movements on a much smaller scale (linearly). Normally, when you hold the mouse cursor still, the slider handle stays still too (there is a 1-1 correspondence between mouse horizontal position and slider handle position, though at a non-1:1 scale). However, if you move the mouse cursor off-end on one side or the other, then (and only in that case) the slider handle will keep moving slowly towards the mouse cursor. All together it's complete nonsense.
