The Mozilla Thunderbird tray icon is not visible (fully transparent). Same with the shutter and caffeine tray icon. Other than that it works perfectly.
Is this with xembed-sni-proxy?
According to zypper se xembed xembed-sni-proxy is installed.

That's a completely unreleased piece of software. It's not passed review yet. Where did you get it?
Just found this; http://lists.opensuse.org/opensuse-factory/2015-10/msg00843.html some openSUSE developer has packaged my unreleased code for current distros. So you're running what I can assume is a completely random snapshot from my code at some point, but I'll have no idea what. I can't do anything with this. (thanks for reporting, frustration isn't directed at you)
(You're welcome. Interesting what ways the code goes sometimes. :) )
I upgraded to Plasma 5.4.3 and the dependency still persists. Are the openSUSE packagers already notified?
The problem is solved for me after upgrading to openSUSE 42.1.
