Hi all

This is my first post so hello to you all and thanks in advance for any help you might be able to offer me.

I've attached a photo of my issue

When i make tight curves with any pencil (which is not smoothed) I get weird marks/artifacts on the turn.

I'm using the latest version of AR5, but it's happened with the earlier versions too. I'm using a Surface Pro 4 i7, latest windows update. I'm using the new surface pen.

I've tried with or without Wintab, Precise tablet and the other options in Prefs but the issue is always the same. It also happens if I just draw with my finger on the touchscreen, or with a mouse.
It doesn't happen when I tick the 'Precise' box in the Pencil Settings and the tool draws clean lines at the curve. However, the precise pencil is pretty bland and I'd love to be able to draw using lifelike pencils as I can in all my other art apps.

Any thoughts?

Thanks

Andy
