描画の上下関係がおかしいとき
必ずしも空間上の上下関係を反映してくれない！
zorderが高いものほど上にプロットされる

Axis3Dを使ったプロットでは、これまで描画順序を変更できなかった？が、v3.5.0で追加された
from python - 3D parametric curve in Matplotlib does not respect zorder. Workaround? - Stack Overflow
computed_zorder=Falseを指定すると手動でzorderを指定できる
code:py
ax = plt.axes(projection='3d', computed_zorder=False)
ax.plot_surface(X1, Y1, Z1,zorder=4.4)
ax.plot_surface(X2, Y2, Z2,zorder=4.5)
blitも関係あるかも
FuncAnimation
blit : bool, default: False
Whether blitting is used to optimize drawing. Note: when using
blitting, any animated artists will be drawn according to their zorder;
however, they will be drawn on top of any previous artists, regardless
of their zorder.
