Subplot horizontal alignment off (y-axes not all aligned) in regular grid

[OminousOmen]

I am trying to make a 2x2 grid of plots, all set to the same size. While the first column of the grid behaves as expected, with the y-axes aligned, the second column has the issue that the bottom right plot is slightly too far over to the left, breaking the alignment of the y axes. Below is my MWE code; I have tried and seen this on both PyPlot and GR backends. Attached is savefig() output from my system.

Julia version is 1.2.0, current released packages for Plots.jl and backends used, on Linux/AMD64.

using Plots
using LaTeXStrings

C_theta = [0.0, 1.13]
C_delta = [0.0, 0.84]
C_M = [5.0, 2.1]

B_theta = [2.42, 0.0]
B_delta = [-0.35, 0.0]
B_M = [2.1, 5.0]

xlimvals = (-0.075, 2.5)
ylimvals_delta = (-0.9, 0.025)
ylimvals_M = (1.8, 5.1)
p_MWE_1 = plot(C_theta, -C_delta, ylab=L"$\delta$", legend = :none, grid = :none, color = :black, xlims = xlimvals, ylims = ylimvals_delta)
p_MWE_2 = plot(C_theta, C_M, xlab=L"$\theta_\gamma - \theta_2$", ylab=L"$M$", legend = :none, grid = :none, color = :black, xlims = xlimvals, ylims = ylimvals_M)

p_MWE_3 = plot(B_theta, B_delta, legend = :none, grid = :none, color = :black, xlims = xlimvals, ylims = ylimvals_delta)
p_MWE_4 = plot(B_theta, B_M, xlab=L"$\theta_\gamma - \theta_2$", legend = :none, grid = :none, color = :black, xlims = xlimvals, ylims = ylimvals_M)


p_composite_MWE = plot(p_MWE_1, p_MWE_3, p_MWE_2, p_MWE_4, layout = (2,2), show = true)

Bump. I am having the same issue. Note that matplotlib handles this correctly.

Julia

x = rand(100); y = rand(100)
f1 = scatter(x, y,)
f2 = scatter(x, y,)
f3 = scatter(x, y)
f4 = scatter(x, y,  yticks=[])
plot(f1, f2, f3, f4)

Python

x = np.random.rand(100)
y = np.random.rand(100)
fig, axes = plt.subplots(2, 2, figsize=(8, 8))
for ax in axes.flat:
    ax.scatter(x, y)

axes[1,1].set_yticklabels(());
