I just switched from Windows 10 to Bazzite with KDE 6. I have experience with linux before, but not as a main OS. I have a Logitech Performance MX. I used SetPoint on Windows to fine-tune things.
For some reason, my scroll wheel acts differently in almost every program. Firefox is the only one that feels normal. My scroll wheel clicks as I scroll, and in Windows that would do 3 lines up or down.
Nothing except Firefox follows the clicking, so all my scrolling is super fine-grained as if I were scrolling with a trachpad. I tried Solaar and that gave me an option to turn off smooth scrolling, but now I need to scroll 6 or more times to see any movement. Increasing sensitivity in KDE just means after 6 times of nothing, the next one is a huge leap. There’s no middle ground it seems and I’m losing my mind trying to fix this.
Is there anything else I can do?
I believe for mouse config in all DEs there are issues with the libinput library and X11 which can somewhat limit config options. If you’re using Wayland then you should find an advanced tab in the mouse options in KDE settings app which may do what you want.
Otherwise imwheel is widely recommended command line tool. There is a comprehensive guide linked below, and the tool can be autostarted in the background once setup.

KDE switched evdev to libinput and dropped some options, including the advanced config tab in the KDE mouse settings.
Here’s all the options I have:
