Jux background slider - color of the background from the slider :-)

HI
Since some days i use the jux background slider, nice funktions.

But now i have a problem, i will show the slideshow not in Fullscreen, the setting Fit Always ist NO.
My pictures dimensions are 2000px x 700 px and they will show responsive.
The Effect ist nice but down of the Slideshow the background (from this Module) is BLACK !
The background from the template is transparent

Where i can change this, for example to color white ?
In the settings i found nothing
Also i look in all css files in the folder modul/jux...

I try many templates, payed, from joomla (Beez and more) and other.... nothing i found.

Thanks for help
