Not sure if this is the answer, but i’ve been having this issue for many months. Not certain if it coincided with the change when I went to iOS 12 beta. But I read comments which seemed to link to the Apple Pencil so I went to Bluetooth settings and removed the Apple Pencil and it’s been behaving since. I had the issue even with no Apple Pencil around I’ll have to see if it works long term but it could be that the palm rejection is kicking in automatically. I had the Apple Pencil and an older Apple wireless keyboard in my Bluetooth settings so maybe there’s a conflict there too. Wonder if someone else can confirm the same result. If so maybe removing and readding the pencil will work. I’m leaving it off for now.
