display problem in library/grid view
Since updating to LR Classic CC I experience a very strange library/ Grid view display behaviour/ Error.
I seems like the grid is somehow "stuck" while scrolling, there is an issue with the update of the thumbnails/ background.
Also when switching to "loupe view" the background is not a solid color, but shows fragments of the grid or previous images.
This image should make clear what I mean:

I'm using Windows 8.1 all updates installed, NVidia Quadro 2000M.
No other issues with LR or Photoshop.
would be nice if this would be fixable...
