2 weeks ago Still a problem as of Firefox Nightly 133 20241023093655, on #GeckoView room as of today
Version de Element : 1.11.82
Version crypto : Rust SDK 0.7.2 (517d99b), Vodozemac 0.7.0Repro after "cache clear and reload", repro to other people than me
STR:
- Open https://chat.mozilla.org/?updated=1.11.47#/room/#geckoview:mozilla.org in a private window
- Go without any login, just viewer
- Chatroom displays OK
- Scroll back to around early October
Expected: View continues to scroll back in history and I can come back to today
Actual: View moves, and collaspes to Sept 30 2024
Note: I can correctly perform the following STRs on https://app.element.io/#/room/#geckoview:mozilla.org without hitting the issue.
Steps to reproduce
In the Matrix Foundation room (#foundation-office:matrix.org) whenever I scroll up past a certain point element-web "flashes" momentarily and then recent messages disappear from the timeline. Attached is a video demoing this.

The "flash" happens around 0:04-0:05.
Outcome
This persists across refreshes and even persisted across an upgrade from v1.11.47 to v1.11.48. I haven't tried a "clear cache and reload" since I suspect it might fix the issue and it might be useful for debugging. I can only reproduce this in my desktop and not my laptop with the same setup (matrix account, same firefox version and plugins).
