The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
User Interface upside down
I have my interface on the canvas element, and the Render Mode of the camera set to Screen Space.
I made a build in virtual reality mode.
I don´t know why, but my interface is appearing upside down when I run the app on Hololens. Why? The screen appears also cut off a little bit on the borders.
Here is the configuration of the Camera (on the left) and of the Canvas (on the right).
