   Confirmed on master as well. Note this doesn't happen for PDF, so it's an eps-only bug.

   This bisects to c712f35, #21395

   @anntzer did you have time to look at what went wrong here?

   Oops, good catch. The fix is

   i.e. _print_ps needs to have an explicit bbox_inches_restore kwarg (due to the implementation of signature sniffing in _switch_canvas_and_get_print_method). I'll try to write up a PR in the coming days, but anyone should feel free to adopt the patch if they can get this in faster.

   Note that this is actually a regression in 3.6.0 that has been around for the whole 3.6 release cycle, so I guess it's technically not release critical for 3.7, but perhaps still a good idea to fix asap.

    I am experiencing the same problem using inset_axes and savefigure() as pdf with the option bbox_inches='tight'.

    import matplotlib.pyplot as plt
    import numpy as np

    x = y = np.arange(-3.0, 3.0, delta)
    X, Y = np.meshgrid(x, y)
    Z1 = np.exp(-X**2 - Y**2)
    Z2 = np.exp(-(X - 1)**2 - (Y - 1)**2)
    Z = (Z1 - Z2) * 2
    
    fig, ax = plt.subplots()
    im = ax.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,
                   origin='lower', extent=[-3, 3, -3, 3],
                   vmax=abs(Z).max(), vmin=-abs(Z).max())
    cb = plt.colorbar(mappable=im)
    plt.show()
    axins = inset_axes(ax, width='20%', height='20%', loc='upper right')
    Z2 = axins.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,
                   origin='lower', extent=[-3, 3, -3, 3],
                   vmax=abs(Z).max(), vmin=-abs(Z).max())
    x1, x2, y1, y2 = -1,0,0,1
    axins.set_xlim(x1, x2)
    axins.set_ylim(y1, y2)
    rectpatch, connects = ax.indicate_inset_zoom(axins, edgecolor = 'k',alpha=1, lw = 1)
    connects[0].set_visible(False)

    @Hexanders I think your problem is slightly different as it only shows when you include the inset axes. Please open a new issue so that we can track it.
