In Xwayland's xwl_unrealize_cursor(), the x_cursor is cleared up only when a device value is provided to the UnrealizeCursor() routine, but if the device is NULL as called from FreeCursor(), the corresponding x_cursor for the xwl_seat is left untouched. This might cause a segfault when trying to access the unrealized cursor's devPrivates in xwl_seat_set_cursor(). A possible occurrence of this is the client changing the cursor, the Xserver calling FreeCursor() which does UnrealizeCursor() and then the Wayland server sending a pointer enter event, which invokes xwl_seat_set_cursor() while the seat's x_cursor has just been unrealized. To avoid this, walk through all the xwl_seats and clear up all x_cursor matching the cursor being unrealized.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
