This was an intentional change in feb574f. The issue was that adding two masks did not give proper full coverage of the image causing compositing artifacts.

However, here it seems there is no AA at all (hard to tell from just seeing the image). It might or might not be a real issue here.

This is why it is always important to attach .blend file which demonstrates the issue.

Ok, there is AA in the mask, but it seems to be not enough to give smooth edges. Will try to tweak some parameters to solve both of this problems..

Any news here?
I can confirm that although anti aliasing works, it was much better before.

This is a know issue, a limitation of the current alias algorithm/implementation.

We currently have the AA node. From workflow point of view masks can be added and AA afterwards.
For more complex setups use Cryptomatte.

My proposal would be to use the SMAA operators for AA in ID Mask with the default settings. How to use these operators can be found in AntiAliasingNode::convertToOperations.
