I am using chromium 1.2 with the dist_texture and tilesort SPUs. I modified the dist_texture SPU to support GL_RGBA instead of GL_RGB. It kind of works, but some textures appear garbled, or have parts of other textures in them. I can't figure out where along the line this is happening. So, I have a few questions. Does anyone know why this is happening? If not, how can I follow a texture through chromium's pipeline to see what is happening? Why doesn't the dist_texture SPU work with 1.9 (chromium crashes before any code in the SPU is even executed)?
