As I am not really familiar with Wine (I am with Linux itself) , is there something I can tell to my users to change a setting, so it works for them?
For the time being you could ask your users to use wine-9.0 as a workaround.

Also note, SARTrack does NOT use 'themes'. It is a basic Windows-XP program.
However, the application does use themed painting, probably Delphi uses it.
And the problem is not in the 'painting' if I understand you correctly; it actually does not add the actual string to the combobox.
Looks like that, yes.
