Black boxes around application fields in VMware View PCoIP session

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.

 Downgrading the virtual machine hardware version
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.
