Some pixel data was blitted into the middle of the batch: 0x00843000 - 0x008431a0. That the initial byte is page aligned makes me suspicious of a TLB error. Earlier, we have 0x0083d18c: 0x54300804: XY_COLOR_BLT (rgb enabled, alpha enabled, src tile 0, dst tile 1) 0x0083d190: 0x03f00480: format 8888, pitch 1152, rop 0xf0, clipping disa bled, 0x0083d194: 0x00000000: (0,0) 0x0083d198: 0x03250446: (1094,805) 0x0083d19c: 0x07529000: offset 0x07529000 0x0083d1a0: 0xfff6f5f4: color as the only thing blitting with 0xfff6f5f4; which would fill 0x07529000 - 0x79f8e00 so not overlapping with the dead zone in the batch. None of the 3DSTATE overlaps the batch. It could have been a result of an earlier batch that we don't capture; but atm TLB is my prime suspect.
