Steps to reproduce:
1.Open the ThemeViewer and select a random theme (e.g. TelerikMetro)
2.Click the "Show Form" button, related to "ribbonbar & backstage view, status strip". As a result a RadRibbonForm is shown. Notice that it has a form icon and a QuickAccessToolBar.
3.Click on the arrow button in the QuickAccessToolBar and select "Show below the Ribbon".
Note that the BackColor behind the form's icon is not correct.

Workaround: this.radRibbonBar1.RibbonBarElement.CaptionFill.Margin = new Padding(-20, 0, 0, 0);
