Package: libgl1-mesa-dri:amd64 Version: 13.0.6-1+b2
Architecture: amd64 Debian Stretch Hello, during debugging a self-developed program I have noticed some memory leaks found with Valgrind, which are caused by OpenGL functions glClear and glXChooseVisual. I attach the valgrind report vg.txt and the file osal2_win_plugin_ogl_fct_scene_enter.c, in which the function glClear is called at line 25. See also: https://community.amd.com/thread/168964 Best regards, Christian Kuhn
