Hello,
we are using the RadRibbonWindow in our WPF Application. Unfortunately, in the current version (2015.1) of the WPF controls, the RadRibbonWindow has a strange Margin on the right Border when Maximized. Also it seems like, that the content on the left is cut. It feels like the position of the Window is not correct. You can see through to the desktop, even when the Window is maximized.
I tried to override the Template but I couldn't find the Margin causing the problem.
I've also tried to use the new Internal Builds, but it wasn't fixed so far. In the 2014 version of the controls, everything worked fine.
The attached screenshot shows an empty appliction where the bug occures. I've changed my background color to black, so you can see it easily.
Best regards
