Element freezes for 15 seconds when switching to DMs metaspace #20143

Open turt2live opened 2 years ago

turt2live commented 2 years ago

Presumably because it's trying to render some thousands of rooms

novocaine commented 2 years ago

@turt2live can you provide more detail about how to reproduce this please?

turt2live commented 2 years ago
  1. Have lots of DMs
  2. Click DMs metaspace
  3. Element freezes for 15 seconds

I can only assume it's because the room list is terrible at rendering so many rooms so quickly.

novocaine commented 2 years ago
  1. Do you mean lots of separate DM rooms open? How many?
  2. Do you mean the "People" metaspace?

Does the same thing happen for home?

t3chguy commented 2 years ago

This will be because the DM metaspace removes the height limit on the People sublist so if you have a lot of DMs then the lack of lazy rendering will really hurt

turt2live commented 2 years ago

err, yes, sorry: People metaspace.

as a more accurate count from the issue description: I have about 2000 DMs.
