KNOWN ISSUES

Below you will find a list of known issues. These issues are defined as bugs, or at times missing features, that is known to the development team and are being actively investigated or developed.

  • Please note that Depth is still in BETA: Distortion on Objects when Depth Feature is enabled – When the Depth feature is enabled for ISAR, there is a distortion on objects and menus that can best be seen when the object is close to the user. It affects especially the top left corner of the object. 
  • Please note that Depth is still in BETA:  With Depth Alpha enabled there is an outline around Objects in the Color of the Camera Background – With Depth Alpha enabled and the Alpha channel of the camera set to 0, you can see an outline around the edges on an object in the color of the Camera's Solid Color. This can best be seen, if another color than black (e.g. red) is used. 
  • Oculus Client Application can only be used when both Controllers are in use – When the user only uses one controller, the other controller does not work in the client. It could be observed that if only the right controller is active, this controller could not be used and the ray of that controller stays at one place. 
  • Please note that the Android Client is still in BETA: Android Client sometimes shows a Black Screen after connecting – When connecting the Android Client to ISAR, the screen turns black and the user has to press either a button on the device or turn the device from portrait to landscape. This behavior could not be observed for all Android device types. On some devices it can be observed once, but then not again until the device is left alone for a certain amount of time (usually 10 - 15 mins).
  • Please note that Depth is still in BETA:  Small black colored parts of Objects become pixelated and semi-transparent in Android Client with Depth Alpha enabled – With Depth Alpha enabled, smaller black colored parts of an object get transparent/ semi-transparent and pixelated.
