I doubt that. Does the problem happen with every stamp you've tested, or only certain stamps? Is this all on your BOOX tablet?

Hi Mike,
I've done some further testing.

• It doesn't seem to matter if the pdf is clipped or not, nor how much it is clipped.
  
• It doesn't happen every time, but it's pretty close (maybe 98%)
  
• Which stamp doesn't seem to matter.
  
• It also happens with the highlight tool, but the size of the highlighted area seems relevant - the bigger it is, the greater the offset. (I use the highlighter to blank out unwanted artifacts in some PDFs)
  
• It doesn't happen with the line tool (at least not that I've been able to detect)
  
• The text tool is very mildly affected: when I've typed the text and complete the entry by touching the stylus to another part of the screen, the text will bump to the right slightly (maybe just 2 or 3 pixels)
  
• When using the snipping tool, the selected area will almost always shrink from the outline I drew.  E.G. I start at the top left, open out the selection box by dragging down and to the right, lift the stylus and the bottom right corner of the selected area will jump up and to the left.  This behaviour is exactly the same as what happens with the highlighter.
  
• Placing a piano staff seems unaffected.
  

Yes, this is on my Boox device.  That's actually all I have aside from the trial version on my phone which isn't used at all.
