I have reported the bug in MCPE-169734, However the page became invaild because it was identified as a bug of the texture pack issue, but actually the bug is a general bug of game. I just gave an example by using an HD pack from Marketplace. ALL of HD texture packs when you use then the bug will happen and only happen in Preview 1.20.0.21. In addition, the higher resolution of pack for using, the bigger items in your hands will be.
I am a 3rd party texture pack creator so I can make sure that this is a game bug instead of resource pack!
Vanilla items are not data-driven so that we can not fix it through resource pack, except using attachable... That is so annoying.
That is the detail:
When I use HD texture pack, some items in my hand, their models became bigger than vanilla resolution in both first person and third person. Meanwhile I also found that the bobing and interacting animation of the items are different from before.
Here is the item list that I have found:
Kelp
Sugar Cane
Campfire
Soul Campfire
Brewing Stand
Item Frame
Redstone Repeater
Redstone Comparator
Hopper
Glowing Item Frame
String
Cauldron
Cake
Music disc (Including all variants)
Nether Sprouts
Flower Pot
Chain
Warped Fungus on a Stick
Coal
Charcoal
Snowball
Arrow (Including all potion variants)
Apple (Added in 1.20.50)
Trial Key (Added in 1.20.60)
Wind Charge (Added in 1.20.70)
Wolf Armor (Added in 1.21.0)
Ominous Trial Key (Added in 1.21.0)
Bundle (Added in 1.21.30)

However, this issue has been temporarily closed as Awaiting Response.
Could you please provide examples of 2-3 different HD texture packs with which this issue can be observed?

Hello, I'll try to identify the problem, let me know if you have a different idea.
The HD texture pack changes the resolution of the item (e.g. 16*16 becomes 32*32) to cause the game to want to render, but due to pixel size adaptation issues, the item looks larger.
您好,我来试着鉴定问题,如果您有不同的想法,请告诉我。
高清纹理包因为物品的分辨率发生了变化(比如16*16变成32*32)为导致游戏想要渲染,但因为像素大小适配问题,从而导致物品看起来显得更大。

Still happen in 1.20.0 Release

Affects in 1.20.1, 1.20.10.24 & 1.20.10.25 Preview

This issue is still happening to my game on Windows.

perhaps i came here for help or maybe it was to try to get this bug fixed sooner, dont really know, but there is a texture pack made to fix this bug although in a bit of a janky way.
the hopper block was missed in the texture pack and snowballs and arrows dont get fixed with the same method, so i tried to make a modified version and i fixed hoppers using the existing code, but i havnt been able to fix snowballs and arrows.
i dont know much about bedrock texture packs or making anything for bedrock in general and it took a lot of research just to get it to slightly work on snowballs, and i was hoping to see the work i cannot complete can be completed by another, so i tried reaching someone smarter than me. the maker of the fix texture pack has messages off, and none of the texture pack servers i was in could help, so ig im here now.
this is the original texture pack
and this is my modified version
this image is how far ive gotten in fixing the issue

affects 1.20.50 and 1.20.60.21

I thought I'd try this myself with 1.20.50 now released and it's still there. I'm pretty sure this issue and MCPE-120618 Custom items are rendered too large in third person view - Jira (mojang.com) are the same bug as the issue seems to only apply to items with a format version of about 1.16.100 or higher. Thing is, none of the affected items listed in the description have publicly available json configuration from what I can see.
That is until now. As of 1.20.50 the Apple item was updated to format 1.20.50 (see bedrock-samples/behavior_pack/items/apple.json at main · Mojang/bedrock-samples · GitHub), and as of this update at least (I haven't checked older), it is also affected by this bug:
[media]I had hoped that if there was at least one official item with a more recent format version that I could see how to fix custom items that use features that have more recently been available in newer versions without forcing me to also use 16x16 resolution textures. Sadly, the update to the apple has confirmed that apparently not even vanilla items can be correctly configured to work with both a recent item format version and any texter pack with a higher resolution than 16x16.

also Apple, and Trialkey is affected by this issue.

affects 1.20.80.20 Preview

This affected items list contains the exact same items as MCPE-172710

The list of affected items in the description is the same as the list of affected items in MCPE-172710. This is probably significant, though it's not obvious what the connection might be. It might also be a coincidence.

Note that for wolf armor was added in latest release (1.20.80) which are no longer experimental outside of gameplay

Cobweb is also affected but differently

@unknown, that is MCPE-183464.

The same items in this list are also affected by MCPE-185729.

Died Bundles too

related to MCPE-169764 ?

Issue persists in 1.21.41, it's been a full year and a half, making tons of purchasable marketplace content work miserably.

If I have to guess what happened, they messed up items texture scaling for items that used a format version of above 1.16.100. Not only that, their first person animations are broken

还有一天这个bug就两周年了(

Does this issue still affect 1.21.80 or the most recent preview?
