It would be useful to find the cause of the
warning: function /usr/local/share/octave/4.3.0+/m/plot/util/ishghandle.m shadows a built-in function

You must have an old copy of ishghandle.m somewhere in your
system where Octave finds it.

I think that I inadvertently opened up two bug reports.  I have not done a new hg clone, but can try that.

>> _octave_config_info_ ("hg_id")

As I mentioned in the other bug report #53286, I do get the following warning which appears to be the culprit:
warning: function /usr/local/share/octave/4.3.0+/m/plot/util/ishghandle.m shadows a built-in function

I would guess it is a problem with your particular setup. Make sure you have old octave files mixed up with the new ones.
When you build, make a clean hg clone, bootstrap, etc...

Also, what is you "hg id" (you can check it on octave prompt
as  _octave_config_info_ ("hg_id") ).
I run a recent dev version of octave daily and I have not seen this problem and cannot reproduce it.

I have built Octave from sources and am getting error messages related to the graphics subsystem.

Just entering graphics_toolkit("fltk") (or gnuplot for that matter) give a number of lines such as this:
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    isfigure at line 37 column 10
    graphics_toolkit at line 63 column 5

In fact entering "close all" from the command prompt gives the same behavior.
