David debugged: Courses modal flickering on university app home
David commissioned an investigation into a courses modal that alternated between showing and hiding courses every second on the production Kerra university home page.
David shared a screenshot showing the courses modal oscillating visibly and directed an investigation:
go figure out why this courses modal is flickering every second, showing my courses one second then not the next second
The investigation traced the issue to a polling loop or reactive state that was re-fetching course data on an interval and toggling the loading state each cycle, causing the modal to flash between populated and empty states. David also flagged a related bug in the same session — that clicking the text input on the university home page to open the draft workspace often failed, causing the page to reload and stay on the home page rather than navigating to the workspace.
