I have recently setup a server Windows 2012 with Citrix Xenapp as an application server with published desktops for my users. Randomly when users are logged on and click on the Windows Start Menu, the screen with all the tiles is just blue and the tiles are all gone. They can bring up the Side bar to search for an app and launch but the tiles are missing. They eventually appear but not sure what cause them to disappear or re-appear. Any insights would be greatly appreciated.

Thanks,

I most often see this with older versions of XenApp. Microsoft made significant changes with Server 2012 regarding graphics to support their "modern" design and the WinRT APIs. Unfortunately those changes do cause Citrix's rendering acceleration algorithm to miss refreshes properly from time to time. Citrix has updated XenApp to fully support 2012, but you have to make sure you are running a compatible version *and* have the proper service pack (being on the latest service pack is almost always a good idea anyways.)

Thanks. I will check that I have the latest service pack and see if the problem still comes up.
