Follow-up Comment #2, bug #61365 (project octave):


[comment #1 comment #1:]
> Not sure if this is causing the performance difference for you. But might be
worth a try:
> 
> We had reports from users in the past that had issues with plotting. It
looked like these issues were caused by some OpenGL drivers.
> To prevent these issues from happening, we started bundling a software
OpenGL renderer years ago. That might have been after Octave 4. But I don't
recall the exact timeline now.
> 
> If your hardware drivers work without issues, you could rename the following
file and Octave should be picking up the (possibly hardware-accelerated)
OpenGL driver installed on your system:
> "C:\Program Files\GNU Octave\Octave-6.3.0\mingw64\bin\opengl32.dll"
> 
> The path to that file might be different depending on where you installed
Octave.
> 
> Does that speed up plotting again?
