turn off handwriting on the asus rog touchpad

if it's the light-up keypad on the touchpad, that's the NumberPad, not handwriting. you toggle it by holding the little icon in the top right corner of the pad for a second. people mistake the two all the time.

Two places it can come from, so check both. Windows side: Settings > Bluetooth & devices > Pen & Windows Ink. Turn off the handwriting options in there (the exact wording moves around a bit between Windows 11 builds). ASUS side: open MyASUS or Armoury Crate, depending on which your model uses, and look under the touchpad / device settings for any handwriting or NumberPad feature and switch it off. If it keeps coming back after updates, reinstall the touchpad driver for your exact model from the ASUS support page. A half-updated precision touchpad driver does weird gesture stuff like this. Which ROG is it?
