This is on Dell Precision 9540, Xorg, libinput, i2c_hid driver, 5.5.7 kernel
Scrolling and taps stop working in some of the windows first, then eventually it propagates to all windows.
"libinput debug-events" still shows all the events correctly when this happens, but "xev" does not.
Reloading i2c modules helps to some extent, but only for a while. A real fix is to restart X11.
How to debug further? Where should I report it?
