--- Comment #9 from Kai Uwe Broulik <k...@privat.broulik.de> --- Seems to crash accessing a nullptr returned by glXGetVisualFromFBConfig which according to docs can return null: "If config is a valid GLX frame buffer configuration and it has an associated X Visual, then information describing that visual is returned; otherwise NULL is returned. Use XFree to free the data returned." https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXGetVisualFromFBConfig.xml And it probably does here because you explicitly told it to skip some visuals -- You are receiving this mail because: You are watching all bug changes.
