My Question or Issue

Every few times (not always strangely) when waking up my computer from sleep the volume slider shows the wrong value the music is actually playing at. Clicking on the exact same spot the volume bar is showing then sets the actual volume to what it is showing.

Example: after a computer wake-up the volume shows 50%. The actual volume is much higher (or lower) though (e.g. 100% - you can't see how much exactly because the volume bar obviously is at the wrong spot). Clicking on the exact same spot the volume bar is showing (50%) then sets the actual volume to 50%. Same goes the other way round (clicking on 100% doesn't change the actual volume, but just updates the volume slider GUI). It seems the GUI is stuck and doesn't refresh on a computer wake-up. Or maybe the volume is changed by a third factor on wake-up, but the Spotify Win10 application does not notice this change and therefore displays the "old" value.
