My MSI Clutch GM20 Elite mouse wheel partially works in the Brave browser on Manjaro KDE.
The only way I can get the scroll wheel to work is if I lift the mouse up so the optical sensor is not reading.
I have another computer running Ubuntu and Windows 10 and the issue is non existent.
I have a Corsair wireless mouse and the problem is non existent on the Manjaro system.
I am running the default drivers
