Graphics processing in a client device includes receiving, as part of a vector streaming split rendering process, a bit stream encoding a sequence of shading atlases of the process. Each shading atlas includes blocks. The client decodes a particular shading atlas of the sequence of shading atlases, and determines that a particular block of the particular shading atlas was unsuccessfully decoded. The client identifies a stored block of a prior shading atlas of the sequence of shading atlases as a successfully decoded earlier version of the particular block. The client renders the particular shading atlas using the stored block instead of the particular block.
