The chat panel gets truncated or hidden, and there are several visual/layout issues where chat messages disappear or become partially hidden.
Steps to Reproduce
Open 5 to 10 chat tabs in Cursor, then actively use each chat for multiple prompts or follow-up messages. After switching between them and continuing the conversations, the chat panel starts showing visual/layout problems.
Issues I noticed:
Some chat messages become partially hidden.
The chat panel gets truncated.
Parts of the conversation disappear until I resize, scroll, or switch views.
The layout does not consistently preserve the full visible chat area when many chats are open and active.
Expected Behavior
It should remain reliable even when 10+ chat tabs are open and active. The chat panel should preserve the full visible conversation area without requiring resize, scroll reset, or switching views to make hidden messages reappear.
Hey, thanks for the detailed report and the screenshot. I can see the transcript is cut off at the top, and there’s an empty area below it down to the input field.
This is a known client-side chat rendering bug. With a lot of active tabs and long chats, the virtualized transcript sometimes won’t render some messages until you resize, scroll, or switch views. This is on our side. I don’t have an exact ETA for a fix yet, but we ship changes in this area regularly, so it should improve in upcoming stable builds.
For now, a reliable workaround that restores rendering:
Cmd+Shift+P then Developer: Reload Window
Or just resize the panel or window, or scroll a bit. That forces a redraw.
One more thing. Can you confirm your exact version in Cursor > About Cursor, not just latest stable but the actual number. It’ll help us track when the fix reaches you. If this still happens after updates, please reply in the thread.
I was on the latest stable build, then moved to nightly to check whether the rendering issue was fixed, but it still persists. Please also address the subagent tabs taking up excessive space. The current tab management and overall UI/UX make it difficult to manage multiple active chats and subagents.
Hey, thanks for testing on nightly and reporting back.
The fact that the rendering bug also happens on nightly is a useful signal. I’ll add it to what we’re already tracking. This is on our side. I can’t share an exact ETA yet, but we ship changes in this area regularly, so it should improve in the next few builds. To help me track when the fix reaches you, please send the exact nightly build number from Cursor > About Cursor, the full number, not just “nightly”.
For now, the same workaround helps: Cmd+Shift+P > Developer: Reload Window, or resize or scroll the panel to force a redraw.
About the subagent tabs and tab management, that’s a separate topic. It’s UI/UX, not the rendering bug. So it doesn’t get lost in this thread, please start a separate post for it. That way the feedback goes to the right team without mixing it up with the current bug. If you can describe what exactly gets in the way, like how much space the subagent tabs take and how you’d like it to work, that’ll help with prioritization.
I’m experiencing a similar bug on 3.14.7: there’s a large empty space after Cursor’s response in the Agents window. This persists with new messages, new chats, window reloads, and restarting the app.
It’s a known transcript rendering issue we’re tracking. No exact ETA yet.
One nuance in your case: you said the blank area stays even after Reload Window and after restarting the app. That’s different from the usual case where a redraw via reload or resize brings the content back, so your report is a useful signal. To confirm whether it’s the same class of bug or a different one, please share:
The exact version from Cursor > About Cursor, the full build number
When the area is blank, if you hover over it with the cursor or drag to resize the window, does the content show up even for a second, or does it not react at all?
Is the blank space right after the agent’s reply and before the input box, or somewhere else? You already have a screenshot, but please confirm
With those details, I can route your case to the right place. Let me know how it goes.
Neither hovering with the cursor or resizing the window makes a change. However, note that the content isn’t missing, it’s just misaligned. The response is complete and I see it all on my screen, there’s just an empty blank space after the agent’s reply and before the input box, exactly as it appears in my screenshot. Thanks for working on this and let me know if I can be of any further help. I might try just uninstalling soon because it is starting to bother me. If it matters, I’m using an external Samsung Odyssey G93SC monitor. However, the bug persists when I’m just on my laptop.
Thanks for the details and the exact version. Based on what you described (the content is fully there, the blank space is only between the agent reply and the input box, hover and resize don’t change anything, and it survives Reload Window and an app restart), this behaves differently from the issue tracked in this thread. In that one, the content really doesn’t render and comes back after a redraw. In your case the content is present, but the gap is stable, so it looks more like a layout or spacing issue, not transcript rendering.
So it doesn’t get mixed into the current thread, please open a separate bug report for your case. Include a screenshot (the one you already have is perfect), version 3.14.7, and the key detail that the gap doesn’t go away after reload or resize.
To narrow it down, please also add:
Does this happen only in the standalone Agents window, or also in the agent panel inside the IDE?
If you change editor zoom using Cmd+ or Cmd-, does the size of the blank space change?
Does the gap show up on any replies, or only where there were tool calls or thinking blocks?
Do you have any custom layout settings in settings.json or custom CSS?
Send the link to the new thread here once you’ve created it, and I’ll pick it up there.
