If your Notion sidebar stutters or freezes when scrolling through a workspace with dozens of teamspaces, you are not alone. This lag occurs because the sidebar re-renders each teamspace icon, page preview, and nested item every time you scroll. This article explains why the scroll performance degrades and provides a set of fixes to restore smooth navigation.
Key Takeaways: Fixing Notion Sidebar Lag on Large Workspaces
- Settings & Members > Settings > Sidebar: Disable animated page previews to reduce GPU load during scrolling.
- Collapse all teamspaces: Collapse teamspaces you rarely use to cut the number of visible sidebar items by half or more.
- Use the Windows Graphics Settings panel: Force Notion to use your dedicated GPU instead of integrated graphics to improve rendering speed.
Why the Notion Sidebar Scrolls Slowly With Many Teamspaces
The Notion sidebar is a virtual list that loads every teamspace, every page under each teamspace, and every nested subpage. When you scroll, the app re-renders each visible row. On workspaces with 30 or more teamspaces, each containing multiple pages, the sidebar may hold hundreds of items. The browser or desktop client must recalculate layout, repaint icons, and load page preview images for each row as it appears on screen. This process consumes CPU and GPU resources. If your device uses integrated graphics or has limited RAM, the sidebar will stutter or freeze during scrolling.
A secondary cause is the sidebar’s live preview feature. Notion loads a small thumbnail of each page’s content inside the sidebar. For every visible row, the app fetches and renders that preview. With many teamspaces, the number of simultaneous preview requests can overwhelm the rendering pipeline.
Steps to Reduce Sidebar Scroll Lag
Follow these steps in order. Each change reduces the rendering load on the sidebar. Test the scroll performance after each step.
- Collapse all teamspaces
Click the small triangle or arrow next to each teamspace name to collapse it. A collapsed teamspace shows only its name and hides all its pages. This reduces the number of items the sidebar must render. For teamspaces you do not need to access daily, keep them collapsed. - Disable animated page previews
Go to Settings & Members > Settings > Sidebar. Turn off the toggle labeled Show page previews or Animate page previews depending on your Notion version. This stops the sidebar from loading small thumbnails for each page. The sidebar will show only text labels. - Reduce the number of pinned pages
Pinned pages appear at the top of the sidebar and are always rendered. Open the sidebar, hover over each pinned page, and click the pin icon to unpin pages you do not use daily. Keep only 3 to 5 pages pinned to minimize constant re-rendering. - Move infrequently used teamspaces to a separate workspace
Create a second Notion workspace (free or paid) and move teamspaces you access less than once a week into that workspace. Switch workspaces only when you need those teamspaces. This reduces the main workspace sidebar to only active teamspaces. - Force Notion to use the dedicated GPU on Windows
Open Windows Settings > System > Display > Graphics. Click Browse and locate the Notion executable (usuallyC:\Users\[YourName]\AppData\Local\Programs\Notion\Notion.exe). Select it, click Options, choose High performance, and click Save. This forces Notion to use your dedicated GPU instead of integrated graphics, improving rendering speed. - Clear the Notion cache
Close Notion completely. Press Windows Key + R, type%appdata%, and press Enter. Navigate to the Notion folder and delete the Cache subfolder. Restart Notion. This removes corrupted cached sidebar data that may cause slow scrolling.
If Notion Still Has Sidebar Lag After the Main Fix
Sidebar scrolls smoothly in the web app but lags in the desktop app
The desktop app uses an embedded Chromium engine that may behave differently from your browser. Try using Notion in Chrome or Edge instead. If the web app scrolls smoothly, uninstall and reinstall the Notion desktop app. Also check that your desktop app is updated to the latest version by going to Help > Check for updates.
Sidebar freezes completely when scrolling fast
This indicates a memory or GPU bottleneck. Close other applications that use significant GPU resources, such as video conferencing tools or design software. If the freeze persists, reduce the Windows visual effects: go to System > Advanced system settings > Performance > Settings and select Adjust for best performance. This frees GPU resources for Notion.
Sidebar lag returns after a few hours of use
Notion may accumulate memory over time. Restart the Notion desktop app daily. You can also create a scheduled task to restart Notion automatically at a set time using Windows Task Scheduler. This clears the sidebar cache and resets the rendering state.
Notion Sidebar Performance Settings Compared
| Setting | Effect on Performance | Effect on Usability |
|---|---|---|
| Page previews enabled | Increases GPU load and memory usage | Shows visual previews of page content |
| Page previews disabled | Reduces GPU load by 30% to 50% | Shows only text labels in the sidebar |
| All teamspaces expanded | Renders all nested pages at once | Provides full navigation without extra clicks |
| All teamspaces collapsed | Renders only top-level teamspace names | Requires clicking to expand each teamspace |
Notion sidebar scroll lag on workspaces with many teamspaces is caused by the high number of items that must be re-rendered during scrolling. You can now disable page previews, collapse unused teamspaces, and force your dedicated GPU to reduce or eliminate the lag. Start by turning off page previews in Settings & Members > Settings > Sidebar. For persistent lag, move infrequent teamspaces to a second workspace. As an advanced tip, use the Windows Graphics Settings panel to assign Notion to your dedicated GPU, which provides the largest single performance improvement for scroll-heavy workflows.
