Have you tried the 2.6 release? This should have been fixed long ago.
If 2.6 doesn't work, then try the pre-release, which will very soon
become 2.6.1:

https://virtualgl.org/DeveloperInfo/PreReleases

If none of that works, then please provide information about what
application you are running.

I tried version 2.6.1 and found it still didn't work properly,The application was developed by my colleague with Open Inventor 9.6.My colleagues have developed three applications, two of which can run correctly and the other can't.

Please post the entire trace log, not just the tail.  I need to see where those drawable and context IDs originated.
