Surface Pro 3 Wavy diagonal lines when inking

The SP1 and the SP2 both use Wacom technology what should not have these problems. Also the SP2 has nearly identical hardware, so you'd trade the bigger screen and the less weight for the better pen.

I was wondering:

what does Panos have to say about the issue? He didn't seem like a complete ignorant on his products when you hear him talking.....so?

I've had my Surface Pro 3 since this christmas, and also have been experiencing these wavy/jagged lines. 

One thing I wanted to report on that I haven't really seen mentioned in this forum often is that I have found the issue seems to be closely tied with palm rejection. I can't say if this is the same for everyones device, but on my own Surface Pro 3, keeping my palm off the screen makes diagonal lines nearly smooth, as if there is no problem at all.

Furthermore, on my own device, something I found that's even weirder. If I hold the backside of my device while I'm inking with my palm still on the screen, the problem also is also heavily reduced. 

Here's an image of inking diagonally on my Surface Pro 3. Note that I used a ruler to make sure any deviation is due to the device itself. 

I went to the Microsoft store a couple of weeks ago to see if the SP3's there had the same problem, and of the devices that I tried they all seemed to have the issue. 

Is there anyone else on this thread who can confirm that this problem does/does not affect their device in this way? I find it very strange that putting my hand on the back of my surface would help the inking to the degree that it has

This. We've gone over this point over at the reddit /Surface forums about a month back and our thoughts and experiences echo  this post right on. This is the first I've heard about touching the back but writing with a cloth on the screen (to prevent contacting the screen with your palm) was the best answer we came up with. It doesn't work for my train ride but from home it's doable and means I can take notes again.

Ya, touching the back of my surface pro 3 while I'm inking does seem to diminish the jagged lines. I have no idea why in the heck this would be the case though. Could it be the heat from my hand, or because it is conductive? Or, maybe it's just in my head.
