Zooming in on world map very slow

[warrickball]

I'm trying to place markers on a simple world map and am finding the map takes a very long time (something like a minute) to zoom in on, say, Great Britain. This happens in both the Robinson or Mercator projections. Here's my simple example. Run this and try zooming on Great Britain:

import matplotlib.pyplot as pl
import cartopy

ax = pl.subplot(1, 1, 1, projection=cartopy.crs.Robinson())
ax.set_global()

ax.add_feature(cartopy.feature.OCEAN, zorder=0)
ax.add_feature(cartopy.feature.LAND, zorder=0, edgecolor='black')

pl.show()

I'm running Fedora 35 and installed geos 3.9.2 and proj 8.2.0 through the default repos. I have Python 3.10.1 and installed cartopy with python3 -m pip install cartopy --user, which has given me version 0.20.1. From my matplotlibrc, I think I'm using the TkAgg backend for matplotlib, which is version 3.5.1.

I'll keep experimenting to see if anything jumps out at me. This might be related to #92 but there wasn't any response there.

Well, this is embarrassing. I've opened an issue in the wrong project. Sorry!
