Buggy Scrolling With Fingers/stylus

by ADMIN 36 views

Introduction

As a user of the Surface Book 2, I have been experiencing a frustrating issue with the Xournal++ app, which is a popular note-taking and drawing application. The problem arises when I try to scroll through my notes using my finger or stylus. Instead of a smooth and seamless scrolling experience, the app bugs out and feels like it refreshes to the top of the page multiple times a second. In this article, I will provide a detailed description of the issue, the steps to reproduce it, and the expected behavior.

Operating System and Environment

  • Operating System: Windows
  • Distribution: No response (Linux only)

  • libgtk Version: 3.24.48

Bug Description

When I try to scroll through my notes using my finger or stylus, the app behaves erratically. It feels like the app is refreshing to the top of the page multiple times a second, although it eventually winds up in the right spot when I stop scrolling. This issue is independent of the page count, and I have only a few lines of stylus writing.

Expected Behaviour

The expected behavior is normal scrolling, similar to what happens when I use a mouse. I want to be able to scroll through my notes smoothly and seamlessly, without any bugs or glitches.

  1. Open the Xournal++ app.
  2. Try to scroll through your notes using your finger or stylus.

There are several possible causes for this issue, including:

  • Incompatible libgtk version: The libgtk version I am using (3.24.48) may be incompatible with the Xournal++ app.
