--- Comment #1 from Tom Stellard tstellar@gmail.com --- Can you test this with the latest version of Mesa from git? I was able to reproduce this on the 9.2 branch by running three separate instances of the run_tests.sh script at the same time as the Lightsmark demo. However, I could not reproduce this on master, so maybe it has been fixed.
