Some line appears fine and some started appearing jiggered in Illustrator cc 2017. I have tried to turn off GPU and antialiased is checked but they won't come clear. I reinstalled the Illustrator cc 2017 and even tried illustrator cc 2015 I have but no luck even on different laptops results was the same.

When I open already made files they appear correct but when I do little edit the edited lines even strokes become jagged. 

Kindly help me I am worried and I have the project to complete and this problem is driving me crazy.

I don't know the option got changed or something. I even turned the antivirus off but no luck. Such a bad day.

Hoping for a quick solution from the expert community.

Thanks for your time in advance.

Make sure that  have the most recent graphic driver update installed on you computer. Install, restart and try again.

Hi, check if there are any updates of your graphics card.

Hey, Thank you all for your time. It is solved when I restore my system to an earlier date.
