I work on an N64 emulator (GLupeN64). I received a report from a user that they
had garbled output from the application. They tried it with llvmpipe and it
worked.

The issue report is here:
https://github.com/loganmc10/GLupeN64/issues/102

It includes and apitrace and a screenshot.

I had him disable indirect drawing, and in that mode the application will use
glDrawElementsBaseVertex instead of glDrawElementsIndirect. He said that that
fixed the issue, but it was very slow.
