I had an issue with scrolling. I would scroll down and sometimes it would scroll up. I put up with this for months thinking it was probably a linux issue and would be fixed with updates. Until today when I plugged a different mouse in and realized the problem was my mouse. I tried turning the mouse upside down and rubbing it vigorously across the carpet like reddit suggested but it didn't fix it so I gave up.

As for linux issues I have switched to Wayland full-time after at least 30+ attempts and it seems to work now except for a flameshot issue which I fixed via a kwin rule and my steam client glitches out when I open the library but it fixes itself if I resize the window.
