Well, I just got a response from support about my issue and it seems it's the same problem. There is another work around. Download and re-install an older version of the nvidia drivers May 2017 or earlier. These drivers are not affected by the update Windows pushed out that broke the current drivers. The link to the drivers I was given was: https://www.geforce.com/drivers/results/119403 I would go to the geforce site and look for the specific drivers for your card and re-install. It's much faster than the intel GPU on my system. Hope this helps. Colin...

I'm having a similar issue. Although it also appears randomly when selecting objects from the Library Browser also (not consistently, but from time to time it causes what seems like a product hang but the top menu continues to work). I have tried switching from my nVidia card (GTX950M) to the built in one (whatever is in the Core i7 these days). Choppy 3D but when I try to close the 2nd to last view pane it has the same "hang" on video for me. I have submitted a case also. Will keep an eye on this thread.
