On v2.x, with ipython --pylab=osx:

plot([1,2,3])
gcf().set_dpi(115)

It now displays the result with an image size based on true dpi rather than pixel-doubled dpi used originally. Subsequent attempts to change dpi result in nothing being plotted.

Somewhat related if an OSX backend figure is dragged from a hidpi screen to a low dpi screen or the other way the figure is blanked (the toolbar buttons stays and are even correctly repainted in the right resolution)

The macosx dpi scaling issues were sorted out in #21365 and this seems to work as expected on my local retina display now.
