World Animations and Decals not working/showing

I’m facing this weird issue on a Garry’s Mod clean server on Ubuntu 12.10

I can’t see the animations from other players when they are shooting or reloading, the decals aren’t spawned either.

This is happening with all gamemodes on a clean fresh server.

I’ve searched but found no mention about this issue.

Has anyone got this and found a solution?
