Cutscene Softlocks in Silksong

Enabling Fast V-Sync causes most cutscenes to be completely black and unskippable.
These are my raw reactions to this bug, in the scenarios where I encountered it.
In all clips in this video, I had the Fast V-Sync option enabled (even in the final clip, where the cutscene worked for whatever reason)

Here's the detailed documentation: https://youtu.be/1DcOInTmXx0
