OTF Font Is Rendered Only Once when Converting a Presentation to PDF in C#

We’ve discovered a problem with OTF fonts that we use while converting to PDF. On Ubuntu it seems to work only once and then they are not rendered anymore, some fallback is used instead. The only way to make it work again is to restart a container.

In the attachment you can find an example application and docker image to run it on Ubuntu as well as example and result of the first conversion and consequent conversions.
