Scrolling problems with trackpad #183

Open xlambein opened 7 years ago

xlambein commented 7 years ago

Hello,

I've noticed a bug when using abricotine on my laptop: the "two-fingers" scrolling is not smooth at all. It's hard to describe, but basically, when scrolling a document, the scroll bar will move slowly and kind-of "vibrates" back and forth. This does not happen when clicking on and dragging the actual scroll bar, or when using a scroll wheel on a mouse. I'm guessing this has something to do with horizontal scrolling messing things up?

I've tried recording a video to show the problem, but it's actually quite hard to realize what's happening when you're not the one scrolling yourself. Anyway, here's the recording I've made:

What is your OS?

xlambein commented 7 years ago

Oops, yup, I forgot about that. I'm on Ubuntu 17.04 with Unity, but I already had the problem on 16.10.

Do you get the same issue in this editor: http://codemirror.net/demo/complete.html If possible please try both Chrome (or Chromium) AND any other browser. Can you also get the same issue in Atom editor (https://atom.io/)? Thank you.

The editor works fine on Firefox, but I have the same problem on Chrome. Atom, on the other hand, works well.

OK so this is obviously an issue with CodeMirror in Chromium based browsers. You should maybe create an issue in https://github.com/codemirror/CodeMirror/issues to get this fixed.
