SUMMARY Since upgrading Plasma from 5.27 to 6.0.2, the cursor shakes vertically when moving it horizontally using the touchpad (it acts normally when moving the cursor vertically). It does not return to the position where it should be. This doesn’t happen when using an external mouse. The shaking is very noticeable and makes it very difficult to hit the desired element on the screen. STEPS TO REPRODUCE Moving the cursor horizontally OBSERVED RESULT The cursor moves vertically (up and down) only during horizontal movements. EXPECTED RESULT The cursor moves steadily in a straight line without any vertical deviation.

Please run `sudo libinput debug-events > log.txt`, move the cursor horizontally, and then attach log.txt to the bug report

The pointer motion events reported by libinput has a lot of vertical offset even though it is moved horizontally. So this is an upstream issue, maybe in libinput, maybe in the driver.
