[How to hide vector contour lines?]

Those purple lines are there to indicate the snapping candidates. You can disable them by clicking on the little white triangle next to the Snapping magnet and clearing the 'Show snapping candidates' checkbox in the dropdown panel.

 

 Indeed that was it. Thank you Alfred!

[How to hide vector contour lines?]

Hello,

 

I'm wandering how I can hide the contour lines on vectors, shown while working, but not after export.

 

The red lines are not strokes, they also disappear when zooming in/out or moving the entire canvas? They are not showing on exported images, but are very annoying and they seem to show up randomly on different vectors and text, but not on all.

 

Thanks in advance,

Dimao
