[Interest] Bad PyQtGraph clipping on PDF output?

[Israel Brewster]

I have a PlotWidget containing (among other things) a plot (created via plotItem.plot() and a textItem (created directly and added via addItem). Both plot and textItem have ZValue set. If the textItem has a zvalue equal to or greater than the plot, everything is fine. However, if the textItem has a zValue *less* than the plot, then when generating a PDF the plot is drawn shifted slightly, such that it protrudes outside the view box. In both cases, the widgets display fine, it’s only the PDF output that is messed up. See attached images and sample code.

I don’t know yet if this is a problem with the underlying QGraphicsView, or something specific to PyQtGraph. Anyone have any idea how I can fix this (other than always putting the labels on top)?
