Package: libqt4-opengl Version: 4:4.8.5+git121-g2a9ea11+dfsg1-2 Severity: normal
Programs using qt4-opengl to load GL procaddress using QGLContext::getProcAddress without loading GL (from nvidia) first will load the wrong library. They will end up at /usr/lib/x86_64-linux-gnu/libxcb-glx.so.0 -- but this library is incompatible with the nvidia GL library. The result are rendering problems (and maybe crashes) An example can be found at https://sourceforge.net/p/m64py/discussion/general/thread/ad27e763/?limit=25 -- the only workaround right now is to always load libGL before using qt4-opengl. The problem seems to be caused by QGLXContext::getProcAddress. The second time it gets run it will load /usr/lib/mesa-diverted/x86_64-linux-gnu/libGL.so.1.2.0 even when /usr/lib/x86_64-linux-gnu/nvidia/current/libGL.so.319.76 is loaded (but was not loaded on program start). Maybe this is out of scope for Qt and has to be fixed by nvidia? -- To UNSUBSCRIBE, email to debian-qt-kde-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
