I am experiencing the same issue on Acer Chromebox. Black screen issue. Workaround is to use Linux version - enable Linux support in settings. Then follow https://www.enpass.io/support/kb/general/how-to-install-enpass-on-linux/ to install Enpass for Ubuntu. Stay in sudo mode and run apt-get install libgl1-mesa-glx. If you need Dropbox support, where redirection does not work from Chrome, install firefox. apt-get install iceweasel.
