An unintentional white line at the top of the screen

So my problem is that I have a white line on top of the layout when I'm running the code on an Emulator which cannot be seen on the blueprint nor the preview. That's the emulator's screen (and the white line) Here is my XML:

    <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="112dp"

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <TextView

            android:text="Budapest"
            android:textColor="#fbf6f0"
            android:textSize="25sp"
            android:textStyle="bold"/>
