I'm trying to setup my self-compiled copy of TDE. I opened "Trinity Control Center" and then "Appearance & Themes" and then "Background". There I selected a picture "Aghi" (showing some green tree branches) and pressed "Apply" (then spent like 10 mins for similar steps, never mind these)

As you can see on the screenshot https://i.paste.pics/7kbai.png the background is not changed at all, it's some kind of default picture being there from the very beginning.

On my real computer with TDE from official repository there is no such problem, so I suppose I might have either installed or started TDE in some wrong way on this hacking clean system (which is running inside a docker container, so not even systemd is present there).

Yeah it is odd, cause I can see the picture on my daily use PC with self compiled TDE. I do not think it depends on if you compiled yourself or not, but one can never be sure when working with repositories which change often (see below).

My question is: what process/daemon can be missed or maybe some other reason for this wrong background behaviour ?

AFAIK it is KDED And in kdcop you can see the interface (img attached)

Just to explain why I so much care about background on a development system: it's about bug #3059 (X11 resources leak). After some research I'm almost sure it's about slide show on background window and now I just want to reproduce this bug in "clean lab conditions".

Hmm - I have it running here for a month now

$ uptime 19:08:05 up 27 days, 11:04, 3 users, load average: 0.57, 0.46, 0.29

Could be that something in the background is causing this.
