Grounding problems [SP6]

[Levilente]

Hi!

I've been trying to solve these problems for about a month or so. I installed surface-linux kernel, iptsd and its running fine, i find it pretty usable, but there is a catch. Touch works flawlessly if i hold the device in my hand, or its on the charger on the table without touching the sides, but if its on the table without the charger connected, and i don't ground it by touching its side, the touch sensor goes crazy, does misinputs, loses swipes, does ghost touches. I made numerous custom configs, tried calibrating multiple times, and it doesnt seem to get any better, its unusable without touching its sides, is there any solution to this?

thanks in advance!
