Holes in the room list

[manuroe]

Some holes can appear when scrolling in the room list. There are of 2 types. We can have blank cells or default placeholders:

Note there is a 3rd type of hole. When the allRoomsView is enabled, some rooms can hide and show when scrolling slowly. I can share a video in a private matrix room.

This is still happening, on "filled" rooms as it seems. Needs more debuggin, reopening.

Tracked this down to a RustSDK problem in which the pos query param isn't incremented correct and list diff operations are applied multiple times, which can create duplicates in both filled and invalidated rooms.

We have worked around this client side here but the underlying issue still remains. I've added a lot more logging around the issue to at least give us an idea what to look for. The problem here is that it's reproducible but very hard to track down exactly why it happens and on what level

[stefanceriu]

We haven't seen this for quite some time now so let's close it but leave the duplication detection logging in just in case. This will all be improved anyway when merging lists directly on the rust side

This came back with a vengance in the week before the public launch of EX, so reopening it. It looks like this sort of thing (from June 30th Nightly):

actually, i guess this is now #1157
