One of my customers had some pretty annoying display errors inside VMware View PCoIP sessions when connecting to a Windows 7 desktop. As a picture is worth a thousand words here is an example of the problem:
The solution to this problem was to downgrade the virtual hardware version to version 7.

|This article provides steps to downgrade virtual machine hardware from a newer version to an older version.|
This problem was seen and solved with the current VMware Horizon View version 5.2 on top of ESX 5.0 with Windows 7 virtual machines.
If this workaround isn’t working for you please have a look at the following article (Black Boxes around application fields in VMware View Manager 5.0.x / 5.1.x PCoIP session) or open a support request with the VMware technical support.
At this point I want to thank Michael Kittlaus for his support solving this problem.
Update: This problem is now fixed with Patch ESXi510-201307401-BG for ESXi 5.1.
