Bug report

Bug summary

Figures rendered on my Surface Pro 3 are very blurry. It looks like the figures are scaled to compensate for my device's DPI scaling (natively 1.5x). This hadn't been the case up until recently. Disabling DPI awareness from Windows doesn't help. Using Anaconda 4.2

Code for reproduction

import matplotlib
matplotlib.use('Qt5Agg')

import matplotlib.pyplot as plt
from numpy import linspace, sin

x = linspace(0, 10, 1000)
plt.plot(x, sin(x))
plt.show()
#

Actual outcome

Expected outcome

Until recently I would just get small (no attempt to compensate for HiDPI) figures without any blur, I'm not sure what has triggered the change.

Matplotlib version
