Zephyr requires OpenGL 1.4 in order to render its interface: please keep in mnd this when controlling Zephyr via remote desktop (both from a physical machine or from a virtual machine).


Microsoft RDP (until Windows Server 2019) does not support OpenGL 1.4 - you must use a remote desktop client that supports OpenGL 1.4, for example Splashtop or Hamachi Logmein if your Microsoft RDP version does not support OpenGL 1.4.


Please also note that even virtual machines must have their correct drivers installed. Make sure that you have your graphics drivers up to date. In some rare cases - i.e. when a video card has just arrived on the market - you may need to install the developers NVIDIA driver available at the URL https://developer.nvidia.com/cuda-downloads until the newer version of Zephyr takes care of that.
