[QA] Issues with avatar spawning in densely populated areas

[kwspgoliasz]

Description: In densely populated locations, around 2 avatars have a noticeably prolonged spawning time. The affected avatar is either completely invisible, or covered with a blue outline. In both cases the username tag is always clearly visible. The scale and severity of the issue seems to be related to the number of users present in the same location. In most cases, the avatars are properly displayed after some time passes. The issue has the highest reproducibility at the Ice Poker scene, however, it was also observed at other locations, such as Genesis Plaza. The issue is thought to be related to the problem with large numbers of invisible avatars which occurred during the Metaverse Music Festival.

Steps to reproduce:

1. Load into Decentraland as a guest or via a wallet.
2. Teleport to a densely populated area (ex. Ice Poker - Stronghold)
3. Wait for the avatars to spawn.
4. Walk around the area while looking at the avatars.
5. Observe the issue.

Reproduction rate: 3/5

Results: In densely populated locations, some avatars have a noticeably longer spawning time in comparison to others.

Expected results: All of the avatars are spawned correctly.

Notes:

• The issue was reproduced on both the production and development configurations.

• The issue occurs on both the guest and wallet accounts.
