The latest Patreon demo seems to have an issue with the Rift integration. The demo runs normally with the DK2 disconnected or turned off.
With the DK2 turned on, the following will happen:
Demo will launch with black screen on monitor and warning page on Rift.
Pressing any key will cause the warning page to disappear.
Audio will continue to play.
The blue power LED on the DK2 will remain on.
Nothing will display on the DK2 or the monitor.
Tested with Windows 10 and SDK 0.8.0. Previous Citor3 demos work normally.
