Might also be the logical pixels that make the difference if different scaling factors are used on different monitors...

All three monitors have the same resolution: 1920x1200

Thanks. So this indeed is the same bug that I remember reading about before.
I still can't find the original report. So, marking this one as confirmed.

If I try to remember the details, ISTR that the command window got cut off at or around the width in pixels of the (smaller) primary monitor.

A long time goal is to replace the command widget with a cross-platform Qt widget. That will probably also resolve this issue.

A work-around is to use the largest monitor as the primary monitor on Windows.

Hi Markus,
sorry for the late reply, yes it makes a difference.
If the external monitor is the main monitor the full line is visible, even if the command window is inside the octave main
window (is docked inside / not in separate window). Stefan

What is needed? Is there something a can test or report?

OT: yes, those two bug reports describe the situation I was trying to recall, as the subject recently came up in another discourse discussion. thanks for the pointers to direct that part of the conversation.

Off topic:
Afaict, Octave's interpreter is fine with handling non-ASCII characters on all platforms.
IIUC, Stefan was referring to the command window of the GUI. That might be a combination of bug #60683 and bug #59495. But it might also be something different if it crashes Octave entirely (not just the console).

Anyway, let's try and keep this on-topic.

regarding your pasting crashes, it was mentioned before that the windows interpreter has issues with non-ascii characters.  copy/paste in the windows interpreter can often produce garbage characters, and pasting those back in, or pasting in text from another source with those types of characters in it (sometimes hidden) can cause Octave to crash.

ISTR, there were reports that something was off when a "secondary" monitor was larger than the "primary" monitor and depending on whether the secondary monitor extended the desktop to the right or to the left.

Does changing the primary monitor make a difference to the behavior you observe?

I am working with three monitors, all with the same resolution:
1920x1200.
The configuration is: Laptop with docking-station and two monitors attached to the docking station.
If only a part of the line is visible is in my set-up dependent on the monitor,
e.g. on the build in laptop monitor the GUI is more reliable.
If I move the Octave GUI to the laptop-monitor the whole line can be seen :-)
There seems to be a workaround, if I un-dock the command window the whole line is displayed.
Furthermore, dependent on the total width of the GUI-window it differs how much of the line is hidden.
Attached two screen shots.

P.S.:
The GUI is quite vulnerable against pasting test into the command window, copying test into it can crash Octave.
Since I work with Octave 6.4 for MS Windows I observed at least 10 crashes.

Works for me.

Your screenshot looks similar to bug #53189 (and ISTR other reports I can't find atm).

IIRC, others that reported that issue in the past used a monitor with high DPI or buggy fonts.

Could that apply in your case, too?

I can see only a part of the whole line inside the command window.
