Ghost Elements in UI

Ask the community or our support engineers for answers to questions.

Hi Folks,

This is a bug I’ve noticed since upgrading from version 0.83 - it appears to be on all subsequent versions, I’ve tested each. After running an application which accepts multiple parameters in a sidebar, ‘ghost’ elements appear to be left behind after a few runs. See attached image, the ‘DB Pension - 2nd Life’ is one of the ghost elements I’m referring to. It’s an afterimage of a widget available lower in the page. Does anyone know how to prevent this or has anyone else come across this problem?

Any and all responses appreciated.

Hi @clintonruairi, and welcome to the Streamlit community! :balloon::raised_hands:

Thanks for reporting this issue.

@snehankekre: is this something you may have already come across? I shall report to Devs otherwise.


@Charly_Wargnier I haven’t come across this previously. Just spotted a similar issue on Github: Session-State inheritance bug (greyed-out elements appear on re-runs) · Issue #3768 · streamlit/streamlit · GitHub

@clintonruairi Please feel free to add to this issue and/or create a new one!

Best, :balloon:
