Please keep in mind that the GUI is just a preview, it is far from being

What is happening here is that "less" is fired at startup, because of the
few lines that are printed in the default .octaverc file and the fact that
octave is initially starting in a very small terminal widget (that is not
shown yet). When the terminal widget is finally displayed, then the
terminal is resized, but "less" (the pager) is already running and you get
various funny things, like the ones you observed.
I didn't expect the pager to be active at startup, during execution of
.octaverc. One workaround is to edit the startup file and add "more off" at
the beginning and "more on" at the end. You can then avoid being started
immediately into the pager.

No, it's just the pager waiting for you to press 'q'.

That's the octave GUI crashing.

As you are in the pager, anything that you typed is captured by the pager.

By default, the octave GUI will most probably use an unsuitable font for
the terminal (and the Windows terminal emulation might be buggy as well).
Select "File" menu, then "Settings", go to the terminal tab and select
another font (I'm using "Lucida Console", which works fine).
