Yes, that's what happens. The installer guesses the locale categories which control various regional format aspects (as opposed to the display language) such as date/time and number formats.

That detail is odd; can't tell if it has anything to do with the actual problem.

In the related bug #1346766 Cheng-Chia Tseng wrote in comment #7:

"Qt does not support fontconfig configuration well, the workaround is
to specify CJK font as the first candidate font instead of western font."

That statement fits well with the fact that it worked for you when you changed the display language to Chinese. It would be valuable to know if we can make it work by doing something similar even if the display language is German.

As an experiment I wrote the attached fontconfig config file. Can you please store it as

~/.config/fontconfig/conf.d/65-droid-sans-first.conf

It ought to result in a different output from the command

fc-match -a 'sans-serif'

with a bunch of Droid Sans fonts at the top of the list. The question is if it changes the rendering in qt apps of Chinese content.
