I can't reproduce this with 5.3, and I don't have an up-to-date 5.7
built right now. Can you see if it happens for you with 5.3?
Ultimately, it needs to be borne in mind that do_zoom.c is a hack.
None of Togl, the OGSF library nor NVIZ itself were designed with this
kind of usage in mind. Consequently, do_zoom.c's attempts to reproduce
the context's state are bound to be a matter of trial and error.
