Broadening 3D application display compatibility in XenDesktop – blacklisting, an interim workaround
I was recently asked about a little-known workaround we sometimes use to overcome rare compatibility issues between our 3D driver and certain applications. When we become aware of these issues we work as fast as possible with the 3rd party vendor to rectify the issue and ensure future versions or ours and theirs resolve the issue in whichever product (or both) the incompatibility has arisen. In the interim we sometimes use a workaround known as “blacklisting” to ensure a customer can carry on with zero downtime in production whilst we and/or the 3rd party vendor resolve the issue. As such this is a temporary measure as when the issue is resolved often in the next version of the application or XenDesktop the advice becomes redundant.
We have never published this workaround as it is intended solely as a fallback mechanism to allow a customer to continue unimpeded short-term. However, “a little knowledge” of the workaround has become semi-public and the public advice we found was limited, partial and misleading. As such we felt it was better, to give a full explanation to customers so, that they understood what they were doing and to explain some of the information available. Indeed, “A little learning is a dangerous thing”….
