Bug Description
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.

Thanks for the bug report. I would usually recommend trying MUTTER_ DEBUG_ENABLE_ ATOMIC_ KMS=0 to fix this but your logs seem to suggest that mode is already active.
Please:
1. Try disabling these extensions in case they're having some effect:

2. Try a USB mouse and confirm there is no such lag.
