I didn't until I read this, then I had 2 in a row.
Happened to me a couple of times this evening. It's a wierd effect in VR. The image freezes and if you turn your head there's just blackness off to the sides. I also got an hourglass on occasion.
There is a PC bug report thread here:

Anyone reporting it on other platforms will need to make a separate post in the appropriate forum but if you mention the PC bug report thread then Support should recognise that and use it to help them sort out what is going wrong.
Well it might be Win10, yet I've never experienced it before.
I haven't had it happen since the patch, but I only played 2h yesterday which isn't enough to draw any conclusions.
So I'm guessing this hasn't been fixed yet?
