I was just going to say that I had experienced the same problem but it looks like you got it,
I did have one other issue though- This is my first update in 3 or 4 versions so perhaps this change was intentional but after updating, all my previous sprites work fine. But when I try and make a new one, as in make the collection, make the sprite, at first my sprite was just coming up as a pink square, i fiddled with the shaders and managed to get it to a white square. (note that it looked fine in the collection editor/inspector, but scene/gameview was a flat color). Whats weird is the setting appear to be identical to sprites created in previous versions.
While I was writing this I rolled back to 1.75b3 and took the same steps as above, and everything works fine.
Cheers
