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.
