works fine when using a test source, so i believe this is related to the decklink input chain.

This is NOT related to RGB input:

Also occurs when using decklink camera input, not only decklink slides input.

Sopie fixed it: https://github.com/voc/cm/commit/83114ed6fd3c2a983e977de7af1019daff6dbedd

We should provide a working example config for decklink sources.
