Thank you, it works fine now. But is it on purpose that every mac/qt5
user will now get the following printed?

Terminal type set to 'qt'
gnuplot> plot cos(x)
Error: short read from gnuplot_qt socket while expecting font metrics

Killing it (= right mouse click -> Quit). I'm sorry for not being exact.

Indeed.

Great, thank you. It works as expected now.

Thanks a lot for fixing all the issues and making Qt work again on Macs.

-------------------

Among the remaining "visible flaws" only those come to my mind now:

- the first plot gets too small window and the lower part of the plot
is not visible; the difference is exactly the status bar; the second
plot gets resized and gets the proper size; curiously enough this is
now a problem with both Qt 4 and Qt 5 and must have been introduced
with one of the recent changes (when I last tested only the reported
size was changed, but there was no visible effect)

- the default font is way too small; on my 13" notebook the numbers
are only 1,5 mm high (7 pixels); I don't know the reason, but on wxt
the font looks a lot better; maybe I should test a simple Qt
application to see what defaults it uses

- horizontal scrolling goes in the wrong direction since a while (and
scrolling is way too fast for precise trackpads) – but both "problems"
are present in other terminals as well

- in Qt 5 the application doesn't show any icon (I already
investigated a while back without luck) – that's just cosmetics though
and doesn't hurt functionality in any way
