PyPlot plots to figure window from IJulia. Why is this happening?

Tooling Jupyter-Notebook
1

Running v1.8.0 on an M2 macbook air. When I fire up a notebook and use PyPlot to make a plot, the figure appears in a figure window, not as part of the notebook.

I have tried rebuilding my environment from scratch and the problem persists.

This does not happen on my Intel Mac. I also think everything was working fine last week. Has some new happened to IJulia or PyPlot? Both the intel and M2 are running PyPlot v2.11.0 and IJulia v1.23.3

MWE: Start a new notebook. Type this into the first code cell

x=0:.01:pi; y=sin.(x); using PyPlot; plot(x,y)

and see if the plot goes where it’s supposed to.

Seems that my startup.jl file has caused the problem. Having
using PyPlot
in there got IJulia really confused. Now when I run the code cell the using PyPlot command generates some annoying output

but everything works.

The annoying message came from a different line in my startup.jl file. I do research in mixed precision computations and had been playing with this

set_zero_subnormals(true)

and commenting that out got PyPlot to start without the annoying message.
