Current Behavior

When I use dynamic mask, keying green out of alpha, some shaders causes the keyed out areas to appear black and opaque.

Expected Behavior

the expectation is that keyed out areas in Dynamic Mask remain keyed regardless of the applied shader.

Steps to Reproduce the Bug

1. apply dynamic mask
2. key out colour
3. apply affecting shader

Any additional Information we need to know?

these shaders are breaking Dynamic Mask:

• CRT curvature
• pixelization
• hexagonize
• smaa

Rejected: Not a bug.

The Shader filter itself supports Alpha/Transparency just fine, so some examples not having support for it is not a bug. There isn't even a way for SMAA to have Alpha support, since SMAA itself does not have Alpha support. Similar situations with the other shaders - it would change their entire meaning.
