@eugen-b: I don’t install MATLAB via the AUR package, because it is a hassle. I can only install it via a web installer and to install it via the AUR package, I have to download the whole application, pack it according to the needed format and then install it via the script. I just install it via the official MATLAB Linux installer and then make my own .desktop file. I would also love to have an AUR script for the web installer, but I don’t have a reason to write or maintain one. Installing it manually is really easy, but I guess for depency issues like this it would be good.
I am also on the latest release 2020a, so this can’t be an issue. It used to work yesterday, so I guess the latest pango update broke it. I guess there is a bug there or MATLAB just does rely on the older pango version.
