same as title, but its just the UI moving, including inventories, the pause menus, and any menu acessible while in a world, exept for replay mod ui elements. all the areas you click on are in the same place, its just the textures that move. also im runnung an enormous amount of mods, but none which modify the UI other than sodium and reeses sodium options. EDIT: it doesnt move up, it moves relative to the crosshair. There is an inaccessible option in the code that turns the mod off if you are in a gui, but it isnt in the menu or the config files. implementing that might fix it?

This bug is really annoying. I reproduced it without any issues. The dynamic crosshair is a very nice and cool feature, but because of this bug it's very annoying. I hope it gets fixed sooner.

Here's a video demonstrating the bug. Running it on 1.20.1. I am positive that this is not a compatibility issue with another mod. There's no other mod that could be causing this.

Thanks for the feedbacks!
However, I still have no idea about what went wrong. I've tried many of the actions in your video, including opening chests, inventory, changing resourse packs......, and I've also tried installing sodium and reeses sodium options, but failed to reproduce it.

I was able to remove this issue by adding a few more mods to my configuration. It is not really a fix for the bug. This must be an incompatibility with another mod I had. I will make a breakdown soon and update you with the fix I got.
If you can't wait - probably the mod called bedrockify. I am saying probably as because this is only a speculation I have currently. I installed a few mods alongside Real Camera and it magically fixed itself, but yeah, I can't say it's completely fixed, but rather less visible or impactful. I think that the bedrockify mod changes some UI stuff like an animation when opening your UI and that basically removes the weird offset, but you can still see it if you move your camera before you open a UI element, you will see a really thin outline at the border of the screen where it shifted a little then it goes back in place. In most cases you don't notice it or it's not there at all, the bug is still there you just don't see it anymore. (or at least if you don't pay attention to your side view you won't see it). Until I confirm which mod breaks it and that bedrockify helps you a little this should stay as a speculation or a possible community fix. I hope I get down to which mod breaks it, it might take a while though since I use more than 90 mods at a time (and yes all of them are client side only).
