So I've got a pen issue and I've sort of figured out what it is. If I use the pen (in any app or program), my pen just jumps up and makes straight lines when I wanna write just above the center of the screen. I noticed that it only happens when I put my palm on the screen and then write, if I don't put my palm on the screen, I don't have that problem. So it's not a calibration problem, it's the palm rejection that's messing things up. Is there any way to solve this? I really don't wanna send my SP3 to MS, because last time I sent something back, I didn't get it back until 3 months later, I'm kinda afraid to send anything now. I've got a i5 128gb sp3 with windows 10 on it. I've tried replacing the battery, calibrating the screen, n-trig calibration app and sort of everything else I read on this forum.
