imshow does not immediately update shared axes #6922
Description
On master:
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax1 = fig.add_axes([0.1, 0.1, 0.2, 0.2])
ax2 = fig.add_axes([0.35, 0.35, 0.6, 0.6], sharex=ax1, sharey=ax1)
ax3 = fig.add_axes([0.1, 0.35, 0.2, 0.6], sharex=ax1, sharey=ax1)
ax1.plot([1, 10])
ax2.plot([2, 20])
# ax3.plot([3, 30])
ax3.imshow(np.random.randn(10, 10))
plt.show()The two axes with the lines do not react to the changed xlim and ylim from the imshow call until one forces a redraw, such as by resizing the window or using a zoom tool.
This problem turned up in #6759.

Does it apply to 2.x too?

Yes, I checked just now with the latest 2.x and the result is the same.

Possibly related to #6890.

Unfortunately, applying #6890, at least in its present form, does not solve the problem.

The behavior is the same in mpl 1.5.1, so it is not a regression. I don't consider it a blocker. I'm going to shift the milestone.

This looks fixed on master to me; feel free to re-open if it's still a problem.
