Public bug reported:
I have an X1 carbon 9th gen with a 4k screen where I use 200% scaling.
Unfortunately, the touchpad feels laggy and imprecise when trying to hit
click targets.
Switching to X11 helps as well as the flat acceleration profile in gnome tweaks.
I feel like this is related to how gnome or libinput upscale mouse movement.
