Try the OpenGL switcher app first.  Many times there is a problem with the hardware-accelerated OpenGL drivers provided by a hardware vendor rather than the software versions supplied by a developer such as Microsoft.

Also, is there a simpler example than semilogx?  Does the same thing occur with plot()?


plot (1:10, 'r', 'LineWidth', 2)
plot (1:10, 'r--', 'LineWidth', 2)

what is the size of the data you're using with that plot function? using a small sample I cannot reproduce this crash in Octave 9.1.0 on Windows 10.


>> semilogx(1:10, 1:10,'r','LineWidth',2)
>> semilogx(1:10, 1:10,'r--','LineWidth',2)


both plot fine with no crashes.

changing the data to span/include 0 values makes no difference:


>> semilogx(-1:10, -1:10,'r','LineWidth',2)
>> semilogx(-1:10, -1:10,'r--','LineWidth',2)


both plot fine.

If you can, please provide either your input data or a reasonable data set that produces the crash so we can try to recreate the issue.

Second thought, can you try using the OpenGL switcher app to see if the OpenGL driver is the issue? You may be using your graphics hardware's opengl driver, and switching to the one bundled with Octave may avoid the issue. If you used the .exe Octave installer there should be a Shortcut in the octave folder of your Start menu.  otherwise see https://docs.octave.org/latest/Hardware-vs-Software-Rendering.html

This code works perfectly:

semilogx(resampled_rtings_target_new(:,1), resampled_rtings_target_new(:,2), 'r', 'LineWidth', 2);


And this code crash



semilogx(resampled_rtings_target_new(:,1), resampled_rtings_target_new(:,2), 'r--', 'LineWidth', 2);
