Moving your mouse, then scrolling to a different hotbar slot, snaps the camera to a random direction

I have the same problem as your @LauraH . As soon as I switch to a different hot bar using the mouse wheel, my screen suddenly changes position (I look straight ahead without using the mouse wheel, and after using it, the screen changes to down or behind me).

I have same issue as @LauraH . When changed hotbar using mouse wheel, camera position changes randomly both fps and tps. It began to occur after v1.21.121 update.

I'm playing Bedrock on Realms with my friends, but they don't have any issues. The common factor is that they use nvidia RTX gpus, but I’m using Radeon. Could this be related to the issue?

(By the way, that is not happened when using game pad or playing on Nintendo Switch.)

@jagnięcina2 Unfortunately, I have a 3060 RTX Laptop GPU graphics card on my pc and I have the same problems as I described earlier.

Same issue. This is not only a pain, it is detrimental to play. Just when your getting ready to fight zombies and scroll to your sword, but instead you turn your back on them and they attack. This must be fixed soon, it makes the game unplayable.

Thanks for the information so far.

Realms were mentioned below, does this issue occur in local, singleplayer worlds as well?

Are there any device details that are affected? Is this only occurring when using a particular mouse, or touchpad? Do you have any other input methods/devices or apps that could be contributing to the issue?

I was unable to reproduce this issue using the scroll wheel on my mouse. However, I can reproduce it consistently (100% repro rate) by using an AutoHotkey script that triggers a scroll wheel action when another key is pressed. This may be related to MCPE-231137.

The provided script makes it so that pressing the C key triggers a scroll wheel up action.

To use the script,

1. Go to AutoHotkey.com and press the Download button.

2. Download and install AutoHotkey v1.1 (not v2.0).

3. Double-click the script to run it.

@Mega_Spud The problem occurs for me in single player local worlds. I do not have Realms.
You also asked about other devices…interestingly I get the problem with my wireless logitech mouse but not with a wired mouse. I have no other input devices.

@Mega_Spud Yes, this issue occur in local singleplayer worlds too, both survival and creative. I tried two mouses logi’s G600(wired) and MX ERGO S(wireless), the result is not changes. It is not occur when I use gamepad(Dualshock4, DualSense) or Java Edition.

Still happening as of new update Bedrock 1.21.122

@Mega_Spud I have done further testing and found that:
- I get the problem with my Logi(tech) M240 (wireless) silent touch mouse
- I do not get the problem with Logitech M185 (wireless) and Logitech B110 (wired)

@LauraH I did a similar thing in my search for a solution. My newer mouse, the Clutch GM 11 Gaming Mouse, which I use every day without any problems in other applications, has a problem with the scroll wheel in game Minecraft, while my older mouse, the Ravcore Tempest (RAVMYS45156), it doesn't have this problem, it works normally.

@LauraH you are my new hero. I just received my new Logitech M185 wireless mouse and it cured the bug. My camera/view no longer shifts while scrolling through the hot bar. Just for kicks I plugged the old Logitech M310 wireless mouse back in and the bug returned so maybe something to do with certain drivers not playing nice with Bedrock? I’m not a tech so I’ll leave that up to them. I’m just happy to be able to play the new texture packs I spent money on that became unplayable. Thanks again for the input.

at least it works with my other mouse. Thanks @LauraH! My other mouse its not very good or sensitive but at least it works till now. Hope mojang corrects this bug and i can play again with my MSI gaming mouse

I found a temporary solution. If you use logi’s mouses, try changing the scroll direction to “Default“ in logi options+. I usually use “Inverted”, but after making this change, it worked. If this applied to you, give it try.

However, this issue doesn’t occur before v1.21.121. I hope it will be fixed…

Solved: I turned off “smooth scrolling” on my logitech using the Logi Options+ software.

Great investigative team work everyone! 😀 @lambx2 @Coach Turning off the smooth scroll for me solve it with my Logitech M240. First time I’ve ever used my Logi Options+ app. 👍

This happens when recording gameplay, if I use OBS Studio everything is fine. Any other software it causes this issue.

Extra background on the bug, it also occurs when i look on a different direction and go to any hud screen (e.g the inventory screen) and go back and swich back and scroll while playing normally.

My MSI Clutch GM11 gaming mouse continues to have the same issue. I've tried changing the scroll wheel usage in the mouse settings, and unfortunately it hasn't improved gameplay.

Thank you for the additional information provided, and for your patience while we actively investigate this bug. We have a new hotfix rolling out today (Minecraft - 1.21.124 (Bedrock)) - while this bug wasn’t called out as a specific fix, please do let us know if the issue is still occurring in this version or not.

Using the AutoHotkey script I provided in my previous comment, I can no longer reproduce the issue when moving the camera and then scrolling to a different hotbar slot. However, if I open a GUI—such as the inventory—move the mouse to a different location, and then close it, scrolling will cause the camera to snap toward the general area of the cursor.

Based on this behavior, the issue was caused by the cursor moving in the background (MCPE-230832). However, since the cursor can be moved while in GUIs, the issue continues to occur there.

Below is a video demonstrating the new behavior:

@キ The same problem occurs when switching between the game screen and the menu screen. In the menu screen, when I change the cursor position, return to the game screen, and use the scroll wheel, the problem only occurs with one switching the slot. Later, after switching to another slot, the camera remains in place and I can play without any problems, but only if I don't switch to other game windows.

This Bug seems to be fixed now

sort of. How did I not notice the comment above until now
