New effect for context menu is distracting

I think interface elements shouldn’t have effects at all.
Sometimes, micro-delays make sense to not accidentally show things when moving the cursor over elements.

For instance, I dislike the modal animation (RS, IT, LW, etc.).
It’s distracting and interrupts my flow.
The builder should be as effective as possible.

Another example

I think it’s nothing more than a bug.
How could this be a feature or intentional effect?
