render_highquality animation. type="bezier" causes overlays to be ignored when frames gets large. #291

Open apsteinmetz opened 1 year ago

The code below produces a render with the overlay ignored. The plot_3d() window looks fine. The render is correct if curve type="cubic" OR the number of frames is "small." I don't know what the cutoff number of frames is.

I don't have the API key for the thunderforest map source, so I ran the following and did not see the same problem (the red line existed). Do you see the red line overlay when you run the following code, and do you still have this problem?
