Follow-up 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?
