We're having a problem where the end-user needs to click twice (not a traditional double-click) on the start menu after login. For example after login, left-click on the Start menu (nothing happens), left-click on the Start menu again, and then it will come up.
Setup:
Horizon brokers: v. 7.3.2
VM Horizon Agent: v. 7.3.2
VM type: Linked clones
OS: Windows 10 1709
UEM agent: v. 9.2.1
It doesn't happen in the template/gold image, just on the Linked clones when provisioned. I've ruled out the UEM agent by removing it for testing purposes.
