Ionic - AlertView Dismiss - SLOW

Ionic Framework ionic-v3

Hi,
i have an application that uses alert views but the process to dismiss them is very slow.

Here I have posted a performance schema. There is a time where no operation is executed and the backdrop showed. Where is the problem???

local packages:

I have solved. In my app.scss I had the override of a class as shown in this code

ion-backdrop {
opacity: 0.5 !important;
}

After I have removed this piece of code, I had no more problems.

This is the new performance schema
