I believe I tried rotating it and disconnecting it a while ago to no avail. I'm running Windows 10 64bit.
Hi. The bug has been reported a second time by a streamer. She told me that it wasn't the first that she saw this happening and that it might be connected to Unity (and/or Windows 10) for some reason. One solution that we found was re-enabling the native Unity screen resolution dialogue. However, the demo does not support this and we will not be updating the demo (due to lack of time) until we have released the full version—Tuesday, January 17th.
