Description:
In Minecraft Java Edition 1.21.11, even on vanilla settings (Fancy graphics, Mipmap 4, no resource packs or shaders), foliage and leaves appear noticeably noisy and aliased compared to 1.21.10.
Previously, similar noise only appeared when using certain resource packs, but in 1.21.11 it is present in pure vanilla. This makes foliage look harsh and pixelated, especially when moving the camera.
Steps to reproduce:
Launch Minecraft Java Edition 1.21.10 vanilla, Fancy graphics, Mipmap 4 → foliage looks smooth.
Launch Minecraft Java Edition 1.21.11 vanilla, Fancy graphics, Mipmap 4 → foliage appears noisy/aliased.
Observe leaves and grass edges, especially while moving the camera.
Expected Result:
Foliage should look similar to 1.21.10, smooth and without noticeable aliasing.
Actual Result:
Foliage and leaves have strong visible aliasing and noise even on vanilla, without any texture packs or shaders.

This appears to be an issue on all versions through 1.21.11 to 26.2-snapshot-2, in both Vulkan and OpenGL. I've also tested it and it occurs on both AMD and Nvidia graphics cards.
Thank you for your report!
We suspect that this does not occur in the latest version of Minecraft.
Is this issue present in the latest version of Minecraft?
Can you record a video of the issue and upload it?
Do you also use some non-standard display settings?

Here it is on the latest snapshot, on both windows and macOS, and with a video. I’m not running any non-standard display settings, and I have seen the issue on all of my friend’s various systems (all with different GPUs and display setups).
Note that the issue is far less noticeable when playing in higher resolution. (for example it’s harder to spot in the mac screenshot, because it has a high resolution display).
I’m sure this issue is to do with mipmap settings or something along those lines, as you can tell in older versions that at further distances, the leaves are replaced with a less detailed texture, which doesn’t have transparency and therefore doesn’t cause this jarring aliasing. Somehow this has been accidentally disabled or broken in 1.21.11.
