So that's actually one of the awful implications of this paper. It's probably actually happening at a rate higher than would be noticed by humans.
If a given piece of silicon is hosing up a GEMM (matrix multiply), in graphics scenarios this may be invisible to the human eye as it could potentially just introduce artifacts in a scene rendering that could be entirely ephemeral to the frame.
In the case of crypto mining though, it's completely possible (probable?) that there are GPUs that can't possibly ever calculate a proper SHA3 hash (see the paper on AES instructions that fail in symmetric ways).
