Comment 4 for bug 1903632

Q. Are you using Xorg or Wayland?
ans: I am using Wayland.

Q. The bug report tag says Wayland, but you filed it under Xorg?
ans: Because typing "ubuntu-bug" in terminal will launch Apport which default shows an option "Display(X.org)", not "Display(Wayland.org)" regradless of what actually user is using. This create a confusion and probably select xorg package Xorg on this website. We need to fix Apport to recognize what user is actually using while showing its option.

Q. Please try both 'Ubuntu' and 'Ubuntu on Wayland'. You can select the session type on the login screen just before entering your password.
ans: I have restart my laptop. Choosed pure "ubuntu" and log in. Opened Firefox and LibreOffice, and tried to scroll. The result is same. It only select all words.

Q. But maybe you can avoid it by using a pure Xorg session.
ans: Are all Wayland issue/problem ignored by Ubuntu-devs?! And for how long?
