Loading the "All Friends" social menu breaks tiled textures across all avatars rendered in game that use Poiyomi,
including other players.
There's a brief hitch from loading the UI that coincides with this.
I've noticed this with the Normal, Detail Normal and Reflection Specular maps. Albedo doesn't seem to be affected.
This persists between avatar changes, avatar resets, and world changes. This can only be resolved through an entire game restart.
It almost looks like the texture's tiling is being changed 0 on a single axis, but there's one portion of the avatar where the texture is fine, then at the end of the tile, stretches.
I've attached a video demonstrating the bug, and a screenshot of the tiling stretching mention above. Please let me know if you need further information.
This issue was first posted in the Poiyomi discord, as the bug seems to primarily affect Poiyomi, but I was directed to post here as well, as the issue stems from the UI Beta.
