I have a late 2014 Retina MackBook Pro that does not want to play well with Horizon.
Whenever I try to connect to our external server, it takes a while to load and then my entire screen is overtaken with a light grey colour background. Everything disappears - the Finder, any menu bars, all controls - and the machine just hangs up. All I can do is force quit and kill the Horizon client. I can't make any preferences changes to the Horizon app because there's no menus to do anything (they all have disappeared).
I don't have any problem connecting to our server on my iPad, Android phone or Windows desktop, but this rMBP has never worked with Horizon. I always get the grey screen of death. I've also tried re-installing the app multiple times (using AppZapper).
Has anyone else experienced this problem?
thanks
