Paint tool - when I touch screen - cursor/dot not landing where expected

Hey folks,

I recently returned to Nomad.
(6 months+of iPad return, fix, break, turn fix, return etc etc)

I remember an old odd thing I encountered from years ago — when using the paint tool, I tough the screen with pencil, but the cursor acts acts strangely

A short video to explain.
Anyone know what’s up?

Many thanks!

Snap radius?

I’ll try!
Thanks!
