Thanks - so I think we're saying that actually the coordinates are about right? The issue is that they go past the edge of the screen if your finger is towards the edge of it? Maybe that's just something that should be documented rather than 'fixed'?
The tap position is interesting though - the tap is reported from the touchscreen as a separate event. However, it's possible in the firmware the coordinates are getting overwritten with the drag coordinates, which might be messing with the position?
