Anyone having display issues with 2015? I frequently get these random lines and text turning in to dots, if I zoom or pan the drawing it goes back to normal. The attached image is from a cover sheet, just lines and text. This happens on plan views as well, the same drawings don't have the issue in 2013 or 2011. Is there a setting that is causing this?

The older ACAD versions were removed from my machine so using them is not an option.
