Logseq Scrolling Lag: Diving Deep into Node Zooming Problems

Hey Logseq users, have you ever experienced scrolling lag when you zoom into a node? It's like, you're cruising along, everything's smooth, then bam – you zoom in and suddenly, scrolling feels like wading through molasses! This article is all about that frustrating issue. We'll dive deep into what causes this, how to reproduce it, and what we can do to make Logseq smoother. Let's get started, shall we?

Unpacking the Scrolling Lag Mystery

So, what's the deal with this scrolling lag? Well, it seems to happen when you zoom into a node within Logseq. Think of it like this: you've got a big page with a bunch of nodes (those little blocks of text). If you scroll through that page, everything is fine and dandy. But, the moment you zoom into a specific node that has a lot of child nodes, that's when the trouble starts. The vertical scrolling, specifically when scrolling up, becomes choppy and slow. It's like your computer suddenly forgets how to handle the input correctly. Interestingly, the lag doesn't always affect all scrolling directions; usually, it's just when you're trying to scroll up. We're talking about a real drag on the user experience here, guys!

This issue has been reported by users and is currently being investigated by the Logseq community. It's important to understand the details so that the community may be able to debug and fix the problem. Here is a breakdown of the problem. This is important to help the team. This problem doesn't arise when scrolling on the main page. It is a zoom-in problem. Specifically, the lag occurs in the upward direction. We'll look at the steps to reproduce it in the next section.

How to Recreate the Bug

Want to see this lag in action? You can try these steps yourself and see if you get the same effect. Following these steps can help you verify the bug and help the team. Here's how you can reproduce the bug and see if you experience the same issue on your end:

  1. Open a Big Page: Start by opening a Logseq page that's pretty large. This page should have a node that has many child nodes within it. The more child nodes, the more obvious the issue will be.
  2. Zoom into the Node: Now, zoom into that particular node. This is where the magic happens (or, rather, where the lack of magic happens!).
  3. Scroll to the End: Scroll all the way to the end of the child nodes. Get to the very bottom.
  4. Try Scrolling Up: This is the moment of truth. Try scrolling up. That's when you'll likely feel the lag – the choppy, unresponsive scrolling.

If you followed these steps and experienced the lag, then you're experiencing the same bug! This helps confirm that it's a reproducible problem, not just a one-off glitch. Feel free to reach out and describe your experience to the team to help verify this bug. What's even more interesting is how a smooth experience changes when the zoom happens. Remember, the same nodes scroll smoothly when viewed from the main page.

Expected Behavior vs. Reality

When we use Logseq, we expect a smooth and seamless experience, right? When we are scrolling, we expect it to be a fluid and reactive process. When we avoid zooming into the node, there is no lag at all. If you're scrolling on the main page, it works just as you would expect. That's the expected behavior. But, with this bug, that's not what happens.

Here's what should happen:

  • Smooth Scrolling: Scrolling should be fluid and responsive, whether you're zooming or not.
  • No Lag: There should be no noticeable delay or choppiness when scrolling, no matter which direction.
  • Consistent Performance: The scrolling performance should be the same, regardless of how you're viewing the nodes.

Unfortunately, as we've seen, that's not always the case when you zoom into a node. This discrepancy between expectation and reality is what makes the bug so noticeable and frustrating.

Tech Specs: Where the Bug Appears

It's important to know the context of the bug. The bug has been reproduced in the context of the following specification.

  • Operating System: macOS 26.0.1
  • Logseq Version: 0.11.0 (87)

This information helps developers and other users pinpoint the issue. If you're on a different platform, or a different version of Logseq, your experience might be different. So, when reporting bugs or discussing them, it's always good to provide this kind of technical information.

Diving Deeper: Understanding the Context

So, what's going on behind the scenes? This problem doesn't occur when you scroll the regular page. It occurs after zooming into a node. This makes us wonder if there's an issue with how Logseq handles the rendering and re-rendering of the zoomed-in content. It could be that the software has to do more work to render the content when zoomed, causing the lag. It's like having a lot of information in a zoomed-in area that needs to be constantly updated as you scroll. It could also be related to how the software manages the visual display or how it handles the input events during zooming and scrolling. When the user zooms, it is important to update the display properly, but it also has to deal with input events at the same time. The increased load can lead to lag. If you are a developer, you might be able to dive in to these details with some debugging. If you are not a developer, it's good to understand the context. This helps you understand why the problem might be happening.
