Revision: 277 http://trac.macosforge.org/projects/xquartz/changeset/277 Author: gstaplin@apple.com Date: 2009-03-03 11:51:51 -0800 (Tue, 03 Mar 2009) Log Message: ----------- Add a torture test for surface creation and destruction. You can verify it with: env LIBGL_DIAGNOSTIC=1 ./testbuilds/triangle_glx_surface It doesn't appear that the X server or libGL clients grow with the test, so I believe the cleanup is occurring properly.
