Ah, sorry, but I didn't bother with screenshots of Absynth at the time and I have now uninstalled Studio One from my Surface Pro.
I did, however, take a screenshot of Sandman Pro which is a VST delay effect. This one was totally bizarre in that although you could seemingly change the size of the GUI, the widgets were all out of scale, meaning that if you tried to adjust something with your mouse the widget that you tried to click on wasn't actually where the graphic was saying it was. Totally unusable.
I posted on the PreSonus forum about this issue and got absolutely no feedback whatsoever, another nail in the SO3 coffin as far as I was concerned. I also messaged Plugin Alliance and got zero response from them too.
Here's a link to the PreSonus post:-

And here's a larger picture of the screenshot:-
In the image, where there appears to be a popup help box, that is where my mouse if hovering. It's the "Width" control which is in the bottom right hand side of the GUI and visible in the middle of the picture.
Totally useless...
