When sending a "vis 1" to a GOP subpatch, it produces a "consistency check failed: canvas_vis" though it seems to work fine. I am wondering if this is still supposed to be true: x == glist_getcanvas(x). In g_editor.c, canvas_vis() starts out with:

void canvas_vis(t_canvas *x, t_floatarg f) { char buf[30]; int flag = (f != 0); if (x != glist_getcanvas(x)) bug("canvas_vis");
