I tried it myself now (with Pidgin and dropbox) in my Leap VM (as mentioned I
cannot reproduce the problem on my real hardware) and it does indeed help, the
icons show up now albeit with a black frame/background.
Unfortunately, it of course also causes a black frame/background on my real
hardware, where it worked before, so there's a regression.

But, I found two proper patches in https://bugs.kde.org/show_bug.cgi?id=355919
and https://bugs.kde.org/show_bug.cgi?id=355504, a package with them is
available here:
http://download.opensuse.org/repositories/home:/wolfi323:/branches:/home:/wolfi323:/test/openSUSE_Leap_42.1/x86_64/

Those do not cause a regression on my real hardware, and even improve the look
of some icons.
There's still the black frame/background in my Leap VM, but I think it's an
accetiple workaround, considering that they didn't show at all before (and
maybe it can still be improved too).

Please test and give feedback!
