problems with deleting lines

Anonymous · ‎09-06-2020

Hi, i have done my first steps with AutoCAD.

i`m using AutoCAD on Mac. By deleting lines, there are strange things in background. i´ve done a screenshoot.

the screenshot shows a deleted line and a not deleted line.

perhaps someone does have an idea.

thank you

Thank you, the change from „metal“ to „open gl“ has solved my problem.
