I don't think so. IMO the first call is a bug.
It's called because the packet is selected and a redissection is triggered
with old frame states (like visited) but only after dissector tables have
been updated. ie wireshark outputs junk.
The culprit is in:
from gtk/proto_draw.c::redraw_hex_dump_all(void)
#if GTK_MAJOR_VERSION >= 2
/* XXX - this is a hack, to workaround a bug in GTK2.x!
when changing the font size, even refilling of the corresponding
gtk_text_buffer doesn't seem to trigger an update.
The only workaround is to freshly select the frame, which will remove any
existing notebook tabs and "restart" the whole byte view again. */
if (cfile.current_frame != 0)
cf_goto_frame(&cfile, cfile.current_frame);
#endif
Setting cfile.current_frame to 0 is not a good workaround.
Patch below should do it.
