iOS 11: Apple Pencil skips, makes dotted lines

Have you made sure the tip is screwed on securely?

I have a 9.7" iPad Pro and the same issue. Turning off all of the zoom settings has not solved the problem for me.

Try going to Settings/general/accessibility/zoom and turning off all zoom settings

I use zoom settings a lot so this is still a bug, even though turning zoom off solves the apple pencil problems.

Until Apple fixes the problem, I suggest turning on the accessibility shortcut feature.

1. Go to Settings/general/accessibility/Accessibility Shortcut

2. Check the Zoom feature

Then, when you want to turn zoom on from within other apps or from the home screen, just triple click the home button. Now, the zoom feature stays on. So, if you triple tap the screen, it zooms in and out like before. And, if you go back to settings, you will see that the zoom feature is turned on. Because of this, your apple pencil will begin to have problems again. However, if you want to turn the feature off while using the pencil, you can quickly do so by triple tapping the home button again. So, if you use the pencil a lot, leave the zoom off and triple tap the home button when you need it. On the other hand, if you use the zoom a lot and the pencil only occasionally, leave the zoom feature on, and triple tap home to temporarily shut it off only when you want to use the pencil.

I have. I actually just spoke with Apple Support. They had me try some things and when I did a System Settings Reset, it did not fix the problem but it actually narrowed the area on the screen where the Apple Pencil was skipping. So it improved it. The next step would be to just back up my iPad and reset it to to factory settings. I have yet to try this, but will do it later this evening and see if it fixes the problem completely.

What if you need Zoom settings?

This worked around the problem for me!
