From Johannes Baeuerle, "The first problem is wrong value of the block size of etc1 textures in the getCompressedSize call in Texture.cpp. With the current block size of 16 the target application crashes with a GL_INVALID_VALUE. The reason is that the calculated size passed to OpenGL does not match the size of the passed data(data pointer,texture width,texture height,spec of etc1).

With a block size of 8 in the getCompressedSize call this error dissapears."
