Only two layers of image transparency are visible.

This can be reproduced using the new canny demo:

python examples/python/opencv_canny/main.py

We log 3 images to the same space.

Only 2 / 3 are visible in the image, although all 3 show up in the hover preview. In this case the canny layer is not visible in the main image view.

If one of the layers, e.g. gray is disabled, then you can see canny:

The generated TexturedRect looks correct:

depth_offset: -3, multiplicative_tint.a: 1
depth_offset: -2, multiplicative_tint.a: 0.33333334
depth_offset: -1, multiplicative_tint.a: 0.33333334
