I am experiencing the same issue. I tried disabling the second monitor, made no difference. I've tried opening drawings from a VW 2016,2018,2019, as well as starting a drawing. At some point soon after I begin to draw anything the screen begins to flash in blocks of color, as described by others. At this point I, and several others in my company, are stuck unable to get anything done on an upcoming project. Please help.
