Almost certainly fixed by #15111 in the next release of matplotlib?
tacaswell commentedon May 20, 2020
We have both
rcParams['savefig.facecolor']andrcParams['figure.facecolor']. The first get used when saving, the second get used when shown interactively. This is a hold over from what the default background color in the GUI was a light gray but you wanted to save it with a white background.This is partially fixed by #15111 (which at at least makes it possible mostly ignore setting the
'savefig.facecolor', however for supporting released versions you will need to set both.QuLogic commentedon May 20, 2020
Going to close this then, since it'll be fixed soon.

Thanks all!
Will use
rcParams['savefig.facecolor']as a workaround in the meantime.workaround for matplotlib/matplotlib#17467
