ChatGPT app fullscreen mode composer issue
OpenAI Developer Community
May 11, 2026
We are building ChatGPT apps that use inline card widgets with a full-screen mode. Across three different apps, we have observed the same issue: when ChatGPT continues generating native text below our inline card widget, the composer inside the full-screen view is gradually pushed downward.
We believe the issue is caused by the native ChatGPT response content being generated in the underlying inline conversation while the widget is open in full-screen mode. Although that native text is not visible in full-screen mode, its layout appears to affect the full-screen composer position.
We can reproduce this consistently:
1. Trigger an inline card widget.
2. While ChatGPT is still generating a long native text response below the widget, quickly open the widget in full-screen mode.
3. The full-screen composer initially appears in the correct position.
4. As the native ChatGPT text continues generating in the background, the full-screen composer is gradually pushed downward.
Expected behavior: the full-screen composer should remain fixed in its intended position, regardless of any native ChatGPT text being generated in the underlying conversation.
Actual behavior: the full-screen composer moves downward as the underlying native response grows.
We have spent several days trying to resolve this on our side, but none of our attempted fixes have worked. Could you please help us determine whether this is a platform/layout issue and advise on how we should handle it?
