@Manuel Castilla (manzanilla) can you review this patch? Also check if the aa operation can be removed

Look good to me. It does fix issue. Only a few changes to follow our code style guidelines:

  • We prefer to always use C-style comments, starting with a capital letter and ending with a full stop. (/* Comment. */)

As these values are used more than once, please define them in "node_composite_util.h" with names CMP_* and replace them in "node_composite_antialiasing.c" too.

@Jeroen Bakker (jbakker) The AA operation can be removed if we do the same on ZCombineNode and DilateErodeNode. It won't affect tests either because they don't reach the code path where it's used.
Don't see a reason why not, only downside is performance, but result is far better. I can create a "Good First Issue" task for doing it. Just need your ok.

Call the setters on SMAA operations constructors with these default values, so we don't need to set them on all future nodes that may use SMAA.

As these values are used more than once, please define them in "node_composite_util.h" ...

Sorry, not in "node_composite_util.h" but in "BKE_node.h".
