android - Background ListView becomes black when scrolling

Question

I have created a specific List which exists out of the following elements to create a scrollable list with every row containing a Image on the left side and some text on the right side:

To begin with a "root" layout :

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:background="#C8C8C8"
    >
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
        android:divider="#C8C8C8"
        android:background="#C8C8C8"/>
</LinearLayout>

and then within the ListView I place the following "row" item :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@drawable/bg_row"
>
    <ImageView
        android:layout_width="wrap_content"
        android:paddingLeft="10px"
        android:paddingRight="15px"
        android:paddingTop="5px"
        android:paddingBottom="5px"
        android:layout_height="wrap_content"
        android:src="@drawable/bg_image"
    />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="5px"
        android:paddingBottom="5px"
        android:textSize="16sp"
        android:textColor="#000000"
        android:layout_gravity="center"
        android:maxHeight="50px"/>
</LinearLayout>

As long as the screen is shown statically (as in no movement) it will be shown correctly, but when I start scrolling through the list the background of the row-item (an "icon" as can be shown in the code) will be shown correctly but the background of the "root" layout will become completely black... when the scrolling stops the background will, most of the times, get back its color... As I test I also added a TextView in that root-element with the same background, this one will detain it's color when the List is scrolled... Any idea why this is happening, and how to solve this?

Add an attribute on the ListView Tag

android:cacheColorHint="#00000000" // setting transparent color
