Scrolling with touchpad (two fingers) stops working after horizontal scrolling with a touch screen
I use a laptop with touch screen running Gnome 3.30.1 on Arch Linux. The problem described here only occurs under Wayland. I can't reproduce using another distribution called Neon developer unstable running KDE Plasma Wayland session on the same hardware.
start Wayland session
open chromium web browser
load some web page
do pinch gesture using your touch screen to increase zoom level of the web page
scroll the web page horizontally using your touch screen
try to scroll the web page vertically with your touchpad (scrolling with two fingers)
