It took me a while to work out that the plotting was deliberately changing behaviour between an open line SimpleLinePlot and a closed shape. I've been using closed shapes - and I think these issues are connected to that. Below - the thin blue line is a rectangle (so the last point is the same value as the first point).
In the first image - when I have a corner I think is exactly on the scale boundary, I get this artifact (I created the scroll bars for rotation, zooming, panning) - I've circled the artifact there in red.

In this second image is perhaps a different error. I've zoomed in a bit on the rectangle. Because it is a closed shape the chart still draws the borders of the shape around the display (even though the true boundaries are outside the plot), but, when we have at least two points outside the display, the math there goes wrong somehow and the chart will position a point invalidly, as shown, that shifts as I rotate the chart.

It takes a bit to set all this up. But basically if you add a SimpleLinePlot that is a closed shape (rectangle, for example), and start zooming in, panning, rotating, I should expect you can reproduce the problem.

I also notice, the behaviour is different if the shape is shifted off in the Z dimension, as opposed to the X or Y. In the picture below, if I scroll the Z dimension, the chart never crops the shapes - but it will if I did the same for X or Y directions.

Thanks for the report. It looks like some sort of clipping bug. However, it is not something we are going to be able investigate in the near term.
