Actually the apitrace shows the problem: 2347 glXCreateContextAttribsARB(dpy = 0x6c00ec0, config = 0x6d081a0, share_context = NULL, direct = True, attrib_list = {GLX_CONTEXT_MAJOR_VERSION_ARB, 4, GLX_CONTEXT_MINOR_VERSION_ARB, 3, GLX_CONTEXT_PROFILE_MASK_ARB, GLX_CONTEXT_CORE_PROFILE_BIT_ARB, 0}) = NULL 2348 glXMakeCurrent(dpy = 0x6c00ec0, drawable = 0, ctx = NULL) = True 2350 glGenTextures(n = 1, textures = &0) ... 2595 glMapBufferRange(target = GL_PIXEL_PACK_BUFFER, offset = 0, length = 0, access = GL_MAP_WRITE_BIT | GL_MAP_INVALIDATE_BUFFER_BIT | GL_MAP_FLUSH_EXPLICIT_BIT) = NULL The game requests a 4.3 context, it doesn't get one, but happily proceeds using a null context as if nothing happened ... until it gets a NULL glMapBufferRange and segfaults. glretrace skips gl calls with a NULL context (because on Windows the OPENGL32.DLL silently drops them so quite a few Windows apps inadvertebntly do it when shutting, so glretrace needs to ignore when replaying on Linux to prevent crashes) -- You are receiving this mail because: You are the QA Contact for the bug.
