[QA] Performance | Backpack slots disappear or stay in loading animation in crowded scenes

Ludmilafantaniella commented 1 month ago

Explorer Alpha build versions:

v0.38.0

Issue Description:

When staying for a long time in a scene with approximately 40 avatars, opening the backpack (press [I]) either causes the slots to completely disappear or stay in the loading animation indefinitely.

STR:

Enter a scene with around 40 avatars.
Stay in the scene for an extended period of time.
Open the backpack by pressing [I].
Observe if wearables and emote slots load correctly.

❌ Actual Result

Backpack slots either disappear completely or stay stuck in the loading animation indefinitely.

✅ Expected Result

Backpack slots should load properly, regardless of the number of avatars in the scene or how long the user has been in the scene.
