Surface Pro 3 Wavy diagonal lines when inking

Good to know.

I've been researching this issue 'cause I have to buy a new computer but I also need some compact digitizer screen that I can carry, but I can tell this wavy line issue pulled me down.

There is nothing to do with it. It's not driver problem, it is poor hardware. I have used numerous tablets, screens, mostly Wacom ones. Although my first one was a nice big Trust tablet, that suffered from the same issue. I installed the fresh driver, re-installed over and over again, and in the end I returned the tablet 'cause I thought that was a faulty one, the replacement was the same. They were nice at the shop, gave me back my money and I purchased Wacom. Had been solved.

Wacom is the industry standard for a reason. A thinner optical layer is NOT worth sacrificing pen accuracy at this kind of scale.

Apparently Microsoft doesn't monitor it's own threads.

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.

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.
