HP Elite x2 G4 (2019)

So the G4 has been out for a while now and haven't seen anyone talk about it.

Anyone have issue with the pen? When I try to write or draw a small circle, it always comes out really ugly. I know pressure sensitivity is enabled, and tried on different apps like OneNote, whiteboard, Snip&Sketch. I even tried putting a small physical guide to draw a circle and it still comes out very ugly.
Is this a pen issue?

Also, the heat is crazy if I leave it at default profile. I actually limit the CPU so it's 3GHz max.

I have a 12" version screen, i7-8665U by the way.
