In Illustrator appear crooked paths. What could be the reason?

Help to understand why were the records show up the outlines when you work in Illustrator?
Before everything was OK.
A bug in the program? Some incompatibility? Or something is configured incorrectly?

You do need a basic brush.
Thanks for the suggestion. Checked. The brush is basic. - Devin.Bosco commented on June 8th 19 at 17:11
