Can you include some screenshots? I do not really understand the issue (and do not have a mac to test on).

@burnpanck Can you try with current master?

attn @astrofrog can you reproduce this?

Will check this out when I have my Macbook to hand

I'm traveling but will try and test this in a few days

Hmm, I don't think I'm seeing this on the latest master branch. All I'm doing is

import matplotlib
matplotlib.use('Qt5Agg')
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.scatter(1, 1)
plt.show()

and then moving between a retina and low-res screen, and everything seems to scale nicely. Let me know if there's other code I could try out.

I see, I'll therefore give it a shot with latest master too! Sorry for not doing that right away.

@burnpanck - are you still seeing this issue with Matplotlib 2.2? (it should be fixed)

No, I don't see the issue anymore either. I'll close the issue therefore. Thanks for all the good work!
