Navbar turns white while transitioning

Ionic Framework ionic-v3
1

Hey,

When trying to get to a new page the navbar is turning white while the transition is happening.
I already saw a solution in which they disabled the transition effect. But that is not what I was looking for.

Thanks in advance!

    <button ion-button menuToggle>
      <ion-icon name="menu"></ion-icon>
    </button>
    <ion-title [hidden]="exam_mode">Prüfungssimulation - {{navbar_title}}</ion-title>
    <ion-title [hidden]="!exam_mode">{{navbar_title}}</ion-title>
    <ion-buttons end>
      <button ion-button icon-only small class="helpbtn" (click)="help()">
        <ion-icon name="md-help"></ion-icon>
      </button>
    </ion-buttons>
