Full backtrace, including X window system error, in the downstream bug: https://bugzilla.redhat.com/show_bug.cgi?id=1311519 The crash occurs when running under X11 when built with Wayland support... that is, the default case, which we test all the time. No clue why it's only crashing for this one user. Possibly unrelated, but Carlos Garcia noticed that's it's odd we use a wl_egl_window* as a GLX window handle ID. Can we really store an integer in a pointer with just a single reinterpret cast like this?
