Re: Reworked qt terminal is much faster – and fails to work on Mac

Just another observation before I test further: it wasn't just a
problem of first-time plot. It was also *sometimes* a problem of the
first plot after closing the plotting window. But that was
semi-random. Sometimes it worked and sometimes it didn't. This could
have been related to whether a new plot was a different one or not or
maybe related to timing.

I would say that it's a problem that
    if (!parent->isVisible())
is hidden inside
    if (s != viewport->size())
because the reverse can be true: c may well be equal to
viewport->size(), but parent may not be visible. I don't know the code
well enough, but it looks like parent is not visible whenever I close
the plotting window (or during the initial plot).
