Hello Luke, After some digging around in the pyqtgraph code I found that the "paint" method of the AxisItem class never gets called using pyside (at least not on my machine, which in deed has a high DPI monitor). Actually nothing thats inherits from GraphicsWidget gets his paint method called ... ever. I searched in the qt docs ways to force que painting of items but I came out short. Updating the related items (update method) produces no effect.
By the way, the Axis items are present in the undelaying scene (and view) or at least they show up at the output of 'items' method. D.
