Hello, Elliot,
Thank you for alerting us to this issue.
I was able to replicate an issue
I have found a workaround:
On a clip that is cropped (layer above):
1. Smooth setting for both resize and debayer in the sizing tab of the Project settings. Bilinear setting for the Monitoring section of the Master Project Settings.
2. In a node tree upstream of any corrections add a layer mixer node.
3. Remove link from the origin to the secondary node that feeds the layer mixer.
4. Right click on the secondary node and add external matte (chose the clip itself)
5. New node will pop up upstream of the secondary node, that is feeding the layer mixer node.
6. Disconnect the key feeder link (Triangle to Triangle) from the EXT MATTE and replace with the image link circle to circle).
This will remove the matte line. The layer mixer node should be on the normal mode.
I have performed the testing on a 6K r3d media in both 11.3.1 and 12 beta 28
