Currently the only way to reproduce the tall grass z-fighting is to place 2 pieces together manually. I have yet to find a generated example.

Well, some people who don't watch the affected versions section will not know if it was marked.
That is kind of their issue.
Let the mods deal with that
Affects 1.13-pre8
Affects 1.13.1-pre1
Confirmed for 1.13.1.
Affects 18w47b
Unable to reproduce in 20w30a
I am unable to reproduce this issue in 20w51a.
I can still reproduce this in 20w51a. You just need to place a few grass there after executing the /tp command, and then move your camera around to see the z-fighting.
My bad. I can still reproduce in 21w03a.
that's kinda intentional
Can confirm in 21w08b. Video attached.
This extends to sugar canes which are adjacent diagonally to tall grass as well.
This probably affects all blocks with x-models which extend close to the corner (as sugar canes do).
Can confirm that this is still an issue in 1.17 and 1.17.1 Pre-release 3. Here are the new seed + coordinates of where this can be seen, as the current information no longer demonstrates this issue.
Is this still an issue in the latest snapshot? I did some testing and I can't seem to reproduce this however the current reproduction steps are now out of date due to the 1.18 generation changes.
You may still be able to use those coordinates, and place the grass yourself.
Can confirm in 21w39a.
Can confirm in 21w44a.
Can confirm in 1.18 Pre-release 5. MC-130709 - 1.18 Pre-release 5.png
Can confirm in 1.18.2.

Can confirm in 1.19.2.
