Describe the bug Running the paper example, on the latest version of jax 0.4.9, generates some high-frequency oscillations in the field that were not present before.

To Reproduce Steps to reproduce the behavior:

run the example_1_paper notebook
Plot the solution field for the helmholtz equation

Expected behavior The new oscillations simply should not be there.

It seems to happen in all Helmholtz solvers now.
