Thank you! Good news: now the stacktrace is useful, and we know where the error comes from, and it's the NVidia proprietary driver (libGLX_nvidia.so.0). Bad news: I do not use the NVidia driver, and there is no way to see what it is doing and how to fix it. I tried to Google this error, but did not find any results so far. Can you try running anki with QT_XCB_GL_INTEGRATION=xcb_egl environment variable? This should make it not use GLX, maybe that will help. -- Dmitry Shachnev
