Ionic 4 - Ionic Refresher Bug

Hello, I’ve faced this issue today. I have implemented ionic refresher on my app in many places, but this time in particular the ionic refresher is displaying a black figure inside.

I have tried doing as the following post but everything stays the same.

The code in my refresher goes like this:

    <ion-refresher slot="fixed" (ionRefresh)="filterAll()">
            pullingText="Pull to refresh..."
  <ng-container *ngIf="!loading">

Is this black square that is an issue or what specifically?

Hello, yes is the black square. Is being shown on all of my devices.

Did you try force background color of your app to white? something like:

<ion-content class="myWhiteBackground">
.myWhiteBackground {
    background-color: #FFFFFF !important;
