Steps:

1. Create a scene with one source, for example an image.
2. Add a Crop/Pad filter to the image source, e.g. cropping from 1920x1080 down to 1280x720.
3. Add an NDI filter output to the image source.
4. View the NDI output in Studio Monitor.

Expected result:
Studio Monitor shows a 1280x720 signal with the cropped image, the same as shown within OBS.

Actual result:
Studio Monitor shows a 1920x1080 signal with the cropped 1280x720 image in the upper left corner of the frame.
