Missing previews, grey boxes in Grid since upgrade to latest LR CC

Hi all, wondered whether anyone else has had these problems since upgrading CC LR and their catalogues?

1. LR suddenly can't seem to 'see' many of the RAWs it saw perfectly well before, posting the usual question marks or exclamations on the image thumbnail. Re-linking one doesn't fix the problem though because the 'find nearby images' command doesn't work when this happens. And...
2. When I flip to Grid view in Library, screen doesn't always refresh properly, either displaying some Grid view images, but with another rendered beneath (such as coffee cup below) or...
3. Dislaying a scary (and increasing) number of blank grey boxes in catalogues that have just been upgraded (2nd screen grab).

Trying to render new 1:1 previews doesn't help...s/w just doesn't do it while this is happening.

However, some of the LRcats that were doing this have mysteriously 'fixed' themselves after an overnight sleep. This makes me question the health of my graphics card, but all was fine before updating s/w.
I'd welcome thoughts on this.

This is very strange indeed. I've never seen something like your first screenshot. Do you have GPU acceleration checked in the Lightroom preferences - Performance? If so, I would start by unchecking that option.
