I have searched for any existing and/or related discussions.
I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
I am using the latest version of Open WebUI.
Installation Method
Docker
Open WebUI Version
v0.9.1
Ollama Version (if applicable)
No response
Operating System
Fedora Linux 43
Browser (if applicable)
Zen (Firefox 149.0.2)
Confirmation
I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.
Expected Behavior
I should be able to scroll without the conversation/chat jumping around.
Actual Behavior
When scrolling up in a conversation/chat it jumps back and forth usually around my queries/questions/messages.
Steps to Reproduce
Open a conversation/chat in Firefox or specifically Zen and try to scroll up. I am scrolling using a notebook touchpad. I am unable to reproduce it in a Chromium browser and this also didn't happen to me with the previous OpenWebUI version.
Scroll anchoring was disabled in a scroll container because of too many consecutive adjustments (17) with too little total distance (1.41176470588235 px average, 24 px total). index.js:7850:54
I have also noticed that while scrolling up does not jump in Chromium it seems to get bit laggy around my queries.

This is definitely a regression. The major new feature is that now it creates and displays tasks with steps (and isn't even completing all the steps it displays). So this is a partially-working feature; and I'm pretty sure that's what also breaks the scrolling.

Looks related to lazy loading/virtual dom - scrollbar jumps around too. It's almost like it's trying to remove elements from the dom within the same message (the whole message can't be displayed).
Changing the windows size mitigates it, until a different sized message is seen.
Firefox on Windows if that matters.

Seems to be related to lazy loading the start and the end of the conversation and the different lenght of messages. Scrollbar is getting smaller and longer as well. Happens on Firefox, Chrome, Edge, WIndows, CachyOS... on mobile and PWA as well

Same issue on my Firefox. However, my Chrome behaves a bit differently: when idle, sometimes the text glitches slightly up and down. Once scrolling, the page doesn't jump around but becomes stuttery and laggy, with the degree of lag fluctuating randomly. Seems only occur with long contexts.

Experiencing the same thing in Firefox, except it is MUCH worse than the example video when you have long messages with things like code blocks in them as it will skip entire messages.

Then start scrolling down, and it dynamically reloads a lot of messages and returns you to the top.
I can't actually scroll down past the first screen of content.
Weird.

This is my experience:
- A long thread, comparing two models.
- Scroll to the top, no problem
- Then start scrolling down, and it dynamically reloads a lot of messages and returns you to the top.
- I can't actually scroll down past the first screen of content.
Weird.
Also when I open or reload a chat I get spawned in the middle of the chat. I am not sure whether that's an expected behavior.
Don't read the chat please. I am braindead.

I don't think the issue went away completely. Now it only happens at the very top of a chat on first load. How to reproduce:
- Use latest Firefox.
- Open chat with enough messages to scroll.
- Reload the page just to make sure we are fresh.
- Scroll to the very top.

You might not actually need to scroll to the top. It's enough to just scroll to the area that isn't loaded yet.
