Resizing a GUI window with Axes3D #1104
Description
If a GUI window with Axes3D is resized, the Axes content is rendered into the resized rectangle, which has a different aspect ratio. This causes the image to be distorted. Together with #1077 this makes 3D plotting very poorly suited for plotting 3D data where all three axes are related, importantly real space data.

I also came across this issue, here some code to verify it.
If the image is set to fullscreen, the axes are distorted but as soon as the plot is rotated or zoomed the figure refreshes and uses correct rendering.
import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D fig = plt.figure(figsize=(11.7, 8.3), dpi=72.0) ax = fig.add_subplot(111, projection='3d') data = np.array([[0.0, 0.0, 0.0], [0.0, 0.0, 1.0], [1.0, 0.0, 1.0], [1.0, 1.0, 1.0], [1.0, 1.0, 0.0]]) #also happens with ax.plot, ax.scatter, ax.plot_trisurf cs = ax.plot(data[:,0], data[:,1], data[:,2], 'b-') ax.set_aspect('equal') ax.auto_scale_xyz([0.0, 1.0], [0.0, 1.0], [0.0, 1.0]) plt.show()This also seems to be related to #1077 in some way, I just could not figure out how.
If you comment ax.set_aspect('equal') the fullscreen plot looks correct.
