Where is it? There's no grass blocks which have the snowy top texture but don't have snow on them!

check, do you use correct seed and coordinats

I looked everywhere. See my screenshot.

but there are grass without snow on your screenshot, you dont see?

Is that grass or gravel?
It's grass with its snowy
state set to true.

OK, my fault. Also treated them as gravel.

But I'm confused why does the top texture changed grey instead of white?

I cant reproduce this bug in 1.13-pre10

Not fixed in 1.13.1, please reopen.

Too bad that it is not intended. The texture is nice, it looks like frozen grass without snow (which happens in places which are so cold that there is no snow)

Still in 1.14

Still present in 20w13b

Still in 1.16.2

also happens in1.16.3
I was unable to reproduce this issue in 20w49a. I've tried all 3 provided seeds and coordinates and was unsuccessful in finding this problem.

Cannot reproduce either. Leaving this ticket open for now as chances are high that someone else will find a new seed/coordinates pair for this issue.
Update:
I found a seed which this issue occurs in. Here is the seed along with coordinates. I've also attached a screenshot. (Can confirm in 20w51a).

I confirm 20w51a.
(NOTE: i checked and it shows "snowy: false" and was rarely generated
using F3 that will show "snowy" states. and i use F3+A that shows normal top grass.)
Can confirm in 21w03a.

I encountered this issue on a new seed. Here is the seed and co-ordinates. Also attached a screenshot.
