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.
