I'm officially flummoxed. I ran rendercheck against both TurboVNC 2.2.5 and TigerVNC 1.8.0 (the system-supplied version in CentOS 7), and the results are basically identical. The only differences had to do with the fact that TurboVNC has depth-15 Pixmaps and TigerVNC doesn't. Both VNC servers use X Render v0.11.
Possible paths forward: 1. Contact the commercial software vendor and ask them how their software tests for X Render support. That may give me a clue how to reproduce the issue locally. 2. Provide me with access to the commercial software so that I can install and test it locally. 3. Provide me with remote access via SSH so I can test the application remotely. For Option 3, your organization would need to pay for my labor.
