Hello,

 I've just tried the demo however everything worked as expected on my end. I've attached a screenshot for reference. Please try to clear your XBAP cache (mage -cc in Visual Studio Command Prompt).

Did you try the standalone demo that is installed on computer as well? That one gives me problems.

Hi Vlad,

You mean in internal builds? I'll pass since this demo isn't that important to me.
