Where is the volume control in "Compact Mode"?

[Steven]

Just found out that it's the 'always on top' setting that makes the volume slider unavailable.  Without that setting, the slider pops up and works fine.

yes, the setting is not being handled - this should fix the issue:

Not fixed yet...

(As before:  I can turn off/on the volume, and scrolling works, but the slider remains unvisible with no transparency - more visible when more transparency.)

I am afraid i wont be able to help further on this as its working fine for me

No problem... (scrolling works, so minor issue)
Thanks for looking into it!
