Problem
You have a Citrix XenDesktop 5.6 environment with the Google Optimization pack installed but some users have reported that they’ve noticed a SwiftShader watermark on various applications such as Google Chrome, Java and Microsoft PowerPoint:
Internet Explorer does not exhibit the same behavior:
Attempting to uninstall then reinstall Google Chrome does not correct the issue:
Solution
The reason why SwiftShader watermark is placed on these windows is because of the d3d9.dll file that was replaced in the following directories:
- C:Program Files (x86)GoogleGoogle Earthclientalchemyogles20
- C:Program Files (x86)GoogleGoogle Earthpluginalchemyogles20
- C:Program Files (x86)GoogleGoogle Earthclient
- C:Program Files (x86)GoogleGoogle Earthplugin
- C:WINDOWSSYSWOW64
To correct this issue, replace all of the d3d9.dll files in the directories listed above with the original Microsoft version as shown here:
With the files replaced, the watermark should no longer be shown (no reboot required):
With the issue resolved by copying the original d3d9.dll file into those directories, Google Earth will no longer run in DirectX mode. The 2 options available at this point is to either recopy the Citrix Google Earth optimization pack d3d9.dll file:
… back into the directories:
- C:Program Files (x86)GoogleGoogle Earthclientalchemyogles20
- C:Program Files (x86)GoogleGoogle Earthpluginalchemyogles20
- C:Program Files (x86)GoogleGoogle Earthclient
- C:Program Files (x86)GoogleGoogle Earthplugin
- C:WINDOWSSYSWOW64
The challenge with doing so is that this may cause the issue explained in one of my previous posts:

The method I recommend to get around this is to not use the x64 version of the d3d9.dll file and use the x86 version instead which wouldn’t require you to overwrite the C:WindowsSysWOW64 file as described here:
