Kodi on samsung dex no subtitles

[beast007]

Hello,

I have a s21 ultra and bought a original adapter from samsung EE-P3200.

Dex is working on full screen and kodi is playing content but subtitles aren't visible..?

Kodi is working on the s21 ultra and subs are playing without any problems without using samsung dex.

Kodi is build 19.1

Does anybody knows what I can try to make this work?

Thanks in advance.

Kind regards
