Today in my work I was shocked because my mask has a strange behaviour. It didn't work like in previous version of Vegas.
I checked it at home but the same issu still exist.
Problem: masks are not covering object. All the time I can see a lot of feathering on the edges (I don't want feather on edges).
In earlier version of Vegas it works well. But in 21... What is that?

This is how bad my mask looks like after applied it in Vegs 21. Look at the edges. They are visible.

This is how my mask looks like. There is no FEATHER on edges. Edges od my mask are perfectly fit.

Gaussian blur effects are applied correctly. Not so low, not so high value.
