Affects 1.21.1 and 24w39a.

I did some testing, and I can conclude at this point that the speed gain of turning off transparency for leaves by setting graphics option to "fast" is practically 0 in the current version of 1.21.1. 

Here are two different perspectives of the same scene with the only difference being either using fast or fancy graphics. The world is a superflat world with all annoying gamerules (like firetick, weather, randomtickrate) turned off. The terrain is 1 layer of bedrock and 200 layers of oak leves. I have uploaded the world as a 7z file attached to this comment.

Here are some comparison images I took with the debug screen. I used pretty default game settings, only unlocking the framerate and otherwise only changing specified values. The options file used can be downloaded here:

The following content of this comment is a long list of large debug screenshots showcasing different levels performance dictated by different specified setups.

First off, vanilla, fancy graphics, looking off into the horizon:

Second, setting the graphics option to "fast". The framerate seems to be identical for the most part, even though you would think the more simplified "opaque" scene would be orders of magnitude faster to render:

For comparison, here is the same exact scene with the mods "moreculling 1.0.0 beta 1" and "sodium 0.6.0 beta 2" both mods using defualt settings, first fancy graphics, then fast.

Here is another angle, looking down and showing a lot more vertical depth and overlapping of leaves. First: vanilla fancy, Second: vanilla fast, Third: modded fancy with default settings, Fourth: modded fancy with moreculling's leaf culling mode set to "depth", and lastly, Fifth: modded fast with default settings:

I can confirm seeing this issue in version 1.20.5

I can confirm that this issue is present in the 1.17.2 release on Nintendo Switch

I get this bug on my Nintendo Switch Lite whenever I'm hosting a multiplayer world, and it's lagging. Or when I'm on someone else's multiplayer world, which is lagging. Edit: Version 1.16.210

I am not sure. It seems to be a hit or miss thing that only  seems somewhat random from system to system.

I can confirm that as well, Numeritos, when I was trying the exact same thing. But I don't think it's that related to this.

This is fixed (Finally yayyy!) for me in 21w10a on my laptop with an i5-1035g1 using the built-in Intel UHD Graphics

I can confirm for 1.16.5

I'm having the same problem on my Switch Lite, although my little brother does NOT have the problem on his Switch non-Lite.

Confirmed for 20w30a

Still present in 20w30a

Bug is no longer present in 20w29a But IS present in 1.16.1! It's been fixed somehow!

Edit: I would mark is as resolved if only I knew how to 🤷‍♂️

I would consider this a duplicate of MC-71767 but I'm not going to close this yet, since this has Mojang priority and MC-71767 doesn't. But it Definitely relates to it!

Where's the bug? That looks like a feature.

Maybe it's to spare performance for the most extreme case of slow hardware? Anyway, it's still present in 1.16.1.

I seem to have accidentally deleted the video but I've quickly made a new one and replaced the link in the report!

I think this issue belongs to the section "Mojang webservices"? And not "Java edition"?

Might wanna change the title to something like "Grass path blocks, soul sand and farmland don't make or have ambient occlusion" Since the bug is "half-fixed"

In 20w10a they seem to make shadows now, but they're still missing ambient occlusion.

If this is a duplicate, then I just wanna say that I tried looking for the original report!
