RPCS3 fixes the rear-view mirror in early Gran Turismo 6

RPCS3 has fixed a corrupted rear-view mirror in early Gran Turismo 6 versions. The bug hit GT6 up to and including 1.05. The fix was announced on the RPCS3 X account on October 8, 2026.

The problem came from overlapping buffers. Kd-11 fixed it with frame-buffer aliasing bias. That breaks ties when a colour and a depth overlap share the same tag. In plain terms, the renderer now knows which layer goes on top, so the mirror draws right.

If you’re a GT6 fan who was stuck on an early version, this is the one that matters. The post doesn’t mention later game versions. The post also doesn’t say which RPCS3 build ships the fix, so check the next release notes before you go looking for it. Fixes like this are small on paper, but they’re the kind of thing that makes an old game playable again.
