You have added this to your code:
$config['wm_vrt_alignment'] = 'bottom'; $config['wm_hor_alignment'] = 'center';
So, I think that it will not overlap the corners if the text is not longer / longer than the image itself, so that it will reach the corners. Perhaps change the wm_padding so that it is wider or wider than the radius of the curve / border?
And, as Alix Axel said, please post the appropriate code for more detailed / useful answers.
