Unwanted scroll to the left/right

ionic-v1
1

Hey!
I have a problem with one of screens of my ionic app. here is the teplate:

<ion-content scroll="false" ng-controller="OptionsCtrl">
  <div class="image-thumbnail_options">
    <img ng-src="{{data.imageData}}"/>
  </div>

  <div class="list raleway-medium format-radio_options">
    <div>
      <p class="primary-color">Select output file format</p>
    </div>
    <ion-radio ng-repeat="item in outputFormatList"
               ng-value="item.value"
               ng-model="data.outputFormat">
      {{ item.text }}
    </ion-radio>
  </div>

  <div class="buttons-group_options">
    <button class="button button-flat" ng-click="show()">
      <i class="raleway-bold primary-color icon-left ion-checkmark-circled"> CONTINUE</i>
    </button>
    <button class="button button-flat" ui-sref="main">
      <i class="raleway-bold primary-color icon-left ion-android-cancel"> CANCEL</i>
    </button>
  </div>
</ion-content>

The problem is, that as the page loads, with the image, it is correctly centered and covers full size, but I can see, that I can horizontally scroll it what results in this:

I have no clue, why it behaves like that so I would really appreciate any help or advice.
From scss:

.image-thumbnail_options {
  overflow: hidden;
  position: relative;
  width: 100%;
  height: 33%;

  img {
    padding: $options_image-padding;
    display: block;
    width: 100%;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
  }
}
