This appears to be an issue with TC invalidation.
Draw 9918:
- Game uploads 832 16x16 Z24 squares to 0x2100 to clear the Z buffer. The squares are not combined into a single transfer because they use BW=1 and offset within pages. However, they should collectively invalidate a region of size 512 x 448.
- There is an old C16 target at the location but it does not get fully dirtied. There appears to be an issue with GSTextureCache::DirtyRectByPage() and/or GSTextureCache::InvalidateVideoMem(). In this case, they don't appear to be computing overlaps correctly between the Z24 area being transferred and C16 valid area of the existing target.
