I can't reproduce this.
However try moving the Destroy_OS_Ctx() call in do_zoom.c to *before*
the point where it tries to redraw everything, i.e.:
#if defined(HAVE_PBUFFERS) || defined(HAVE_PIXMAPS)
/* Done */
/* Reset viewport and draw orinanl view */
GS_set_viewport(a_orig, c_orig, b_orig, d_orig);
Ndraw_all_cmd(data, interp, argc, argv);
