One thing I did different was to change where the background was called from. I did that to make the background behind the Task manager button work. Here is what my files look like

framework-res.apk/res/values/dimens.xml

<dimen name="thumbnail_height">160.0dip</dimen>
<dimen name="thumbnail_width">240.0dip</dimen>

SystemUI.apk

/res/values/bools.xml

<bool name="config_recents_thumbnail_image_fits_to_xy">true</bool>

/res/values/colors.xml

<color name="status_bar_recents_app_label_color">#ffffffff</color>

/res/values/drawables.xml

<item type="drawable" name="status_bar_recents_background_solid">#00000000</item>
<item type="drawable" name="status_bar_recents_app_thumbnail_background">#ff1a1a1a</item>
