Bug when targeting the Windows Creative Update version ?.

If an app is targeted at Windows Creative Update it returns different (wrong) values for Viewport,PreferredBackBufferHeight and PreferredBackBufferWidth. An app targeted at build 10586 returns the correct value for Viewport {{X:0 Y:0 Width:1920 Height:1080 MinDepth:0 MaxDepth:1}}. An app targeted at Windows Creative Update returns {{X:0 Y:0 Width:1280 Height:960 MinDepth:0 MaxDepth:1}}

What type of project are you using? Windows, DesktopGL, UWP?

UWP . I found this while checking why my PickRay class had developed a bug after starting a new project using code from a working project.

More detail on this issue.
