not sure 100% if this is our issue or yours but we recently implemented dark theme using kendo.black.min.css.  On line 3485 (in our version) it applies a glass.png texture to selected objects, giving it a glowing highlight.  That's great.  However, displaying a floating window, it also has k-state-active on it, and we get a horizontal bar in the center of the popup caused by this css.  See photo.
