Surface Pro 3 Wavy diagonal lines when inking

Hello breic,

Thanks for sharing this issue with the Community. I understand that your handwriting on your Surface Pro 3 looks erratic. I'll do what I can to help you with this issue.

In order to address this, we need some further information. We would like images which compare writing on your Pro 3 very slowly and at a more standard speed rather than the Pro 3 alongside the Pro. Also, could you verify that the writing looks worse when writing very slowly rather than very quickly. Is it that way, or is the other way around? Finally, have you installed all updates?

Please let us know so that we can help you further. Thanks again for posting in the Community.

Best Wishes,

On my Surface Pro 3, when I write the line jiggles constantly about 1/2 a millimeter to either side of the writing tip.  Unless I zoom in to 200% (and write twice as large), this makes my handwriting look like I have hand tremors, and the results are unusable, much worse than with my Surface Pro.  

The jiggling is better if I do not rest my hand on the screen to write.  It might even be gone completely then.  But I can't be sure, because I can't write cleanly without resting my hand on the screen.  

Is this normal?  Is my pen/computer defective?  Any way to address the problem?  

Here is an example: 

The top is SP3 and the bottom a Surface Pro.  Compare the two letter l's in "Informally," for example, or the O in "Decomposition."  This is actually the best case scenario for SP3 (writing extremely slowly and carefully) and the worst-case scenario for the SP (writing very quickly).  

Ivan,

It doesn't have anything to do with the pen in the instance of the Surface RT.. If you use a drawing app and draw a vertical line or horizontal line (with your finger or capacitance pen) it is perfectly straight. If you draw anything at an angle slowly, it creates a wavy line. If you draw it quickly, it is straight. This is the same problem that I have seen people complaining about on all of the devices thus far, and likely has to do with either the touch screen or the code used for calculating the line.

I think the problem must be with the pen. I bought a replacement Surface Pro 3 pen and while there are still some calibration issues (particularly in portrait mode), they definitely aren't as pronounced as they were with the original pen included with my device.

Kevin, Surface RT don't have digitizer pen. So problem described above cannot apply to Surface RT.

I had no such problem on Surface Pro 2 either.
