Thanks for the investigating. My test system is a Raspberry Pi 4 running Raspbian (Buster). But I can reproduce this problem on all my systems with armhf cpu. For example I have an industrial PLC (WAGO PFC200) with ARMv7-CPU and docker support which has exactly the same problem. So I am pretty sure that it is the docker image and not the host system.
