How to get a definitive answer about a K component

[DoYouKubuntu]

I'm just wondering how to go about getting a definitive answer on the issue of those pesky icons I mentioned in another thread. I'd like to know--FOR SURE--what it is that controls the icons we see in our panel. See, here's what happened...

I reinstalled K 14.04 a few days ago. That solved various issues I didn't feel like troubleshooting any more, including a missing network connection icon in my panel, and big ugly versions of other icons in my system tray. Then, yesterday, I was tweaking various things, like GTK2/3 settings, logged out, logged back in and my system tray icons had turned back into the BIG UGLY VERSIONS I had before reinstalling K. I want to know why. I've played around with themes and icons [in the file system, not just via settings] and can't figure out WHICH icons are being pulled in for things like volume, battery monitor, etc.

That could be your desktop theme that change your icons in the system tray

No, that's not what's happening. They're the same icons, just BIG UGLY versions of them. Oh, I can make them smaller by adjusting the height of the panel--but that also shrinks EVERYTHING else in the panel, and that's not what I want.
