I am having this issue as well, but in VW 2018! When I zoom in/out, I can see everything, but as soon as I stop, everything disappears. I can highlight objects, but they all disappear. I JUST fixed the whole thing crashing because I was using text. I'm REALLY starting to hate the speed at which programmers are cranking out updates, etc, because it seems that they are now using users as their beta testers and charging us a monthly fee to do their work.
I'm having a similar issue - dimensions are not showing up. Also, the dimensions don't seem to snap to any line. I run the dimension and then they just disappear. The Dimension class is on. I've not had this issue with other files.
