For some areas did, but as can be seen in the previous screenshot, many icons
are still black or missing. So yes, only half success. Besides, I want to know
what causes this :).

Thank you, I checked this one also. It is the from the KDE:Frameworks5 and I
use KDE:Qt5 along with it.

It is KDE.

Thank you, I'll check that one also and try some strace'ing. On the weekend I
won't be near but on Monday I try to debug this further.
