Loading with vertical view

Hi there,

I’ve got a weird problem with your plugin; it loads up with a vertical view, but only very briefly, for a couple of seconds. It looks like this: https://s5.postimg.org/d2w0431cn/GS_logo_slider_problem_1.png

It then goes back to normal, and looks like this: https://s5.postimg.org/612nvmn4n/GS_logo_slider_problem_2.png

Is this a problem with the plugin, or could it be an issue with the theme?
