Created attachment 137091 [details] including opengl_demo.zip valgrind.result glxinfo.txt Hi all, I ran a test program in ubuntu 16.04, mesa 18.1. Please see attached glxinfo.txt for system information and opengl_demo.zip for test program. The test program use create simple shader 10 times. Using valgrind as following 'valgrind --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=20 --track-fds=yes ./es2tri', it easy to get a memory leak report as in attachement. ==24757== LEAK SUMMARY: ==24757== definitely lost: 144 bytes in 2 blocks ==24757== indirectly lost: 8,000 bytes in 40 blocks ==24757== possibly lost: 1,460,261 bytes in 4,429 blocks ==24757== still reachable: 165,485 bytes in 115 blocks ==24757== suppressed: 0 bytes in 0 blocks
Your program appears to be terminating before it reaches eglDestroyContext and the eglMakeCurrent that unbinds the context. With the context and screen not being destroyed, we have no opportunity to clean up, and everything appears to be leaked. If you fix your app to destroy the context, there should be no leaks.
As you said, I changed the exit event loop using "Esc" key, avoiding the error, there is no leaks.
