Bug ID: 105203
Summary: Update to 1.10.0 makes cursor "vibrate" when using
touchpad
Product: Wayland
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: libinput
Assignee: wayland-bugs@lists.freedesktop.org
Reporter: y...@masson-informatique.fr
Hi,
I am using Debian testing on a Dell E7440, which just switched libinput from
1.9.4-2 to 1.10.0-1. When I touch the touchpad, without moving the finger, the
cursor vibrates. It does not depend on the pressure. Cursor does not move much,
but it makes it difficult to click on precise areas.
Do not hesitate to ask if you need more information.
Best regards,
Yvan
