It is just as the question states. the Zoiper Application Icon in Pulseaudio Mixer on ubuntu 16.10 using XFCE 4.0 is so large that I have to use the scroll to see all my playback applications to make adjustments.
Please see the link for a screenshot of the issue, I would like to have the icon the same size as the VLC icon and other playback icons.
Thanks
Brent
