Surface Pro 3 Wavy diagonal lines when inking

I think all surface pro 3 have this issue. If you want to draw a straight diagonal line you have to use a ruler and still you can see a little bit of wave on the line.

I've been fighting this problem with the Surface Pro Pen since I started illustrating on my Surface Pro 3--128 GB model. Whenever I draw slowly, diagonally, or both, the cursor moves up and down as I draw--as if its trying to snap to one of the tiny dots on the screen as I pass them. It is common to every app--Photoshop, OneNote, even if I'm drawing a selection box on the desktop I can see the blue box resizing erratically. I don't know what to do. I've taken all of these troubleshooting steps:

Replace pen battery

Replace pen nibs

Recalibrate pen

Replace pen

Uninstall, reinstall N-trig Wintab

For whatever reason, the problem seems far worse when I rest my palm on the screen.

The photos I have attached show the problem... the grey lines are from PhotoShop while the blue ones are from OneNote. I dont know what to do any more. I'm out of ideas, and I absolutely do not want to reinstall the OS--its not the sort of thing I feel would be a software issue, and I'm up to my neck in schoolwork.

This is not only you....it have been discussed in other topics in this forum. Microsoft know about the issue but I don't know when and if they are going to release a firmware to fix this problem. Do not do a refresh of your surface because is something probably in the driver of the pen or the screen itself.... I think this issue affects all surface pro 3. If you use a ruler to draw diagonal lines it minimizes the wavy lines but they are still there. I hope they fix this soon other wise when people start using this adobe illustrator program that is coming out for the surface more people will begin to complain.

Yep, I am seeing this jitter as well. I've tried across a bunch of apps, and the issue repros consistently. If you draw a straight line slowly, the resultant line (well, the points produced by the digitizer) is wavy. I can produce a video of this to demonstrate the issue if needed.

Wow... How many people have to post about this for them to admit there is a SERIOUS issue here. The pen is almost unusable for taking notes in any science class there diagrams need to be drawn... Let alone trying to do art... This is absurd, and they know it is a **** ntrig hardware issue that they can't actually solve without recalling and rebuilding them. I have been to 3 different microsoft stores and tried 20+ surface pro 3s. They ALL have this issue. The only reason a smooth line can be achieved is when you draw fast enough that it can skip the extremely course hardware detection grid. They really skimped on this.
