At 100% volume, handle appears off center with volume marker

[BrodieRobertson]

Maybe this is stylistic choice but when the volume slider is at 100% the handle appears off center with the dash marking 100% volume

I think this is a known issue, and might be caused by the same issue as described in pop-os/iced#165 (since e.g. the dash on the mouse speed slider is properly centered).
