Can reproduce on fd11e1352d9e0b15d67520354bbbf40c615bf996. For convenience, I quickly created a *minimal working example* from the given code: ```python3 import pyqtgraph as pg from pyqtgraph.Qt import QtCore import numpy as np...

This can currently be reproduced with branch `develop`. As an example, I modified ROItypes.py: ```python3 #!/usr/bin/python -i # -*- coding: utf-8 -*- ## Add path to library (just for examples;...

As far as I know, there is no need to change the z order after changing the background. Please test this: ```python3 import pyqtgraph as pg from pyqtgraph.Qt import QtGui...

@3fon3fonov Yes, for the image exporters, they all have their flaws. That's why I think it would be useful to only have one image exporter to worry about (e.g. matplotlib)...

Wasn't the conclusion we had at the beginning of this discussion, that all exporters inherently have flaws and therefore it would be best for graphics exporters to just have one...
