Do they flicker when you switch from one week to another (old ones disappear, there's nothing for a short while, then new events appear and this repeats for every scroll), or do they continue to flicker as they are displayed without changing to another week?
Comment 2 Quinten Kock 2023-12-01 19:07:41 UTC
They flicker when scrolling (vertically) within the same week. When switching between weeks using the back/forward button the events are fine (but the days at the top like Monday, 27 November 2023 do seem to flicker; there's no text for one frame or so).
