ChatGPT app fullscreen mode composer issue

OpenAI Developer Community May 18, 2026

Hi @Domantas_Vanagas, this does sound like a platform/layout issue rather than something your widget can fully control.

The useful clue is that the full-screen composer moves only while the native response continues growing underneath. That points to the underlying conversation layout still influencing the full-screen view.

Best next step is to email support@openai.com with:

  • the repro steps you shared here

  • app/widget details

  • screenshots or a short recording

  • affected ChatGPT client/version, if known

Once you have the ticket number, please share it here so it can be tracked from the community side too.
