# Steps to reproduce
0. have a mouse with horizontal scrolling functionality (mine is a Microsoft Comfort Mouse 4500 with a tilting action for horizontal scroll)
1. move mouse pointer over the dock
2. use the mouse scroller to scroll horizontally
# What I expect to happen
# What happens
Mouse pointer and everything on screen freezes. After a few seconds it unfreezes, but all the icons from the dock are missing. I have to log out and back in to restore the dock.
# Other info
Slightly similar to LP #1875106, but I’m not using imwheel.
I am using Wayland.
Syslog seems to always point to this one function: ”The offending callback was get_preferred_height(), a vfunc”. I’ll attach the relevant part from one crash.
