Animating mesh's scale make the texture bug.

Hey there. Tried to post it on the Answers, to no avail, so I'm trying here.

I'm making a game where I use mesh animations from time to time. Only one or two use transform's scale animation, but those two cause a texture bug on some devices, like the UVs of the mesh were messed up, and only during the scale animation.

Here is a preview of what happens :


The left cube is with the right texture, the left one got a mix of pure black and white stuff instead.

I tried changing the shader to Mobile/Unlit, Mobile/Diffuse, Unlit/Texture, Diffuse.
I tried enabling/disabling the multithreaded rendering.
I tried playing with the texture compression.

The device that have the bug :
- Lenovo IdeaTab (GPU : PowerVR SGX544MP2)
- Huawei P6-U06 (GPU : Vivante GC4000)
- Samsung Galaxy Pocked 2 (No GPU)

Device that does not have the bug :
- Samsung Galaxy Note 2 N7100 (GPU : Mali-400MP4)

In the Player settings, I use the Graphics Level to Automatic.

The fun stuff : the scaling is not even applied on iOS, like there weren't any animation to start with.

I can do without this but I'd really like to have those animation working properly. Anyone have a way around, a hack or even better, a fix?

 

Bump, still no idea how to fix this. Anyone?
