Description
This only occurs with 2.2rc1 (and the current tip of that branch). The following code:
import matplotlib.pyplot as plt
import numpy as np
gx = np.linspace(-5, 5, 10)
img = np.hypot(gx, gx[:, None])
fig = plt.figure()
ax = fig.add_axes([0, 0, 1, 1])
mesh = ax.pcolormesh(gx, gx, img)
plt.colorbar(mesh)
plt.show()produces:
Traceback (most recent call last):

Seems to have crept in with the constrained layout manager--I'm not sure what the proper fix is.
