Have a similar problem on t480 on kernel 6.0.2-arch1-1. The trackpoint works at first, then the input starts to get "mushy", then (after about 3 minutes of constant use) trackpoint freaks out (cursor teleports across the screen, random rmb/lmb/mmb presses). Disabling/Enabling both trackpad/trackpoint in bios has no effect on xinput cli output. Trackpoint is recognised as "PS/2 Generic Mouse".

The touchpad has three "mouse" buttons on top, and none of these buttons currently function. Using xev does not show any output from these buttons. The touchpad itself works fine. There are two bottom buttons integrated with the touchpad, which do not work consistantly. The left button will sometimes act like a left-click and sometime like a right click, making it hard to move applications on the screen. The right button acts like a left click and only sometimes bring up menus. Trying to change from a left hand to a right hand mouse in mouse options does not change the behavior.
