From the small number of examples seen so far, it looks like just a single bit is being flipped. Let's dump some values to see if it there is a larger pattern here. Furthermore since gem_linear_blits is also showing bitflips on glk, we can rule out the impact of tiling altogether! It just becomes a question of which piece of hw is broken...
