Most likely cause by https://github.com/matrix-org/matrix-rust-sdk/pull/3501, can you please check on the newly released 1.6.9?

Kimiblock commented 5 months ago

Indeed better, though slowdowns when opening the room still happens

Thanks for checking. Loading initial items on opening rooms has been addressed here and deadlocks have been fixed so I will close this issue.

Is that a dead link?

Oh sorry, I had a typo, edited now.

It still occurs to me, 1.6.11

Maybe I should reopen this

We're seeing this super often on 1.6.9 too.

In this video, if you were to have waited longer would the message have appeared in the timeline? If that's true, next it this happens could you add a screenshot which includes the scroll bar?

I believe this might be an instance of the timeline having far too many items loaded (given how long it takes to open the room again) so simply being slow. One trigger for this was fixed in #2969 although there's still another potential way this can happen (albeit more slowly).

Will try. I’m a little sick recently.

FWIW this has been much better with 1.6.11. I don't think I've seen it once.

Kimiblock commented 4 months ago

Seen this again
