This bug still exists, I've posted a potential fix on the mailing list http://lists.freedesktop.org/archives/wayland-devel/2014-December/019003.html The root cause is that the X11 event handler is processed in the middle of frame repaint just a few lines before the animations are updated. So if the x11 event handler destroys the output, the processing of animation events fails. LIBGL_ALWAYS_SOFTWARE=1 appears to be a red herring, though it may influence timing. Mentioned patch was pushed to master some time ago. http://cgit.freedesktop.org/wayland/weston/commit/?id=6deb09ef8a72164947cdfa5f2414e292c7672c9c If the problem is still reproducible please feel free to reopen this bug. Thanks, Dawid |

Created attachment 102732 [details] weston core dump and executable i set the following variable in an x11 terminal: export LIBGL_ALWAYS_SOFTWARE=1 then ran weston. i moved a weston terminal window around a bunch, then closed that terminal window, then then clicked the close button for weston. then the core dumped. i'm running debian jessie + some sid on amd64. i've attached the core dump file and weston binary.
