This is a master bug for performance improvements on CSS shaders. Currently, the implementation is very slow for two reasons:
1. Each time the style changes a new GraphicsContext3D is allocated (and textures, shaders etc.)
2. The shader is not using the accelerated composition and moves pixels from CPU to GPU.
For that reason animations are not smooth and tolerance values used in animation tests are very large.
