Original file is not loading when zoomed in 100%

[Florian O.]

With the Option "Use Smart Previews for image editing" enabled in Lightroom Classic, it usually loads the Smart Preview in the Develop module and only loads the original raw file when zoomed in at 100%.

It started acting weird lately with half of the time not loading the original and getting stucked with a zoomed in and pixelated smart preview. I did not change anything on my setup.

Has this been reported before?

Update: the same goes for the Previews in the Library. Even when I have generated 1:1 Previews, Lightroom ignores them completely and acts as if there are only the smart previews and library previews with the same size. In this situation zooming in does not work at all. 

The only workaround is to delete standard and 1:1 preview and generate them again. Nedless to say that its very anoying and slows down culling and editing a lot.
