[matplotlib/matplotlib] Label subscript cutoff when increasing dpi
Code for reproduction
import matplotlib.pyplot as plt
fig,ax = plt.subplots(dpi=300)
ax.set_ylabel(r"$\frac{E_0}{E_{\infty}}$",
rotation=0,fontsize=30,labelpad=20)
plt.savefig("test.png")
Bug report
Bug summary
When using a (latex) fraction in the y axis the subscript is cutoff when the dpi and fontsize are increased. This behavior does not appear when using the default settings for figure dpi (100).
import matplotlib.pyplot as plt
fig,ax = plt.subplots(dpi=100)
ax.set_ylabel(r"$\frac{E_0}{E_{\infty}}$",
rotation=0,fontsize=30,labelpad=20)
plt.savefig("test.png")
