We are having an issue with a 20 to 30 second black screen on reconnecting a active sessions, in both Win 7 and Win 10 desktops. It happens on both PCoIP and Blast. We tested RDP with no issue, it connects right away. This issue has been going on awhile but most users are login off and locking back in. There is no delay with that, it connects right a away and you see the login process.
