Expected Behavior

It should display my camera without "white" background.

Actual Behavior

When applying the "Background removal" filter on my camera, it works fine on 16:9 but when applied in vertical (StreamElement's plugin), it just shows... white.

If I set blur background is set to 0, it does work perfectly fine. But if I put 1 or more, the camera becomes white as shown above.

Steps to Reproduce

1. Removed blur background and re-applied the filter.
2. Uninstalled the background removal and re-installed it.

Additional Notes / Screenshots

This is how it looks like when the blur background is set to 4:
