[x264-devel] Does anyone find bugs on PSNR calculation of x264?

[kenter]

I was trying to disable Top-Right prediction modes on x264 now, I find the
psnr difference is rather low for enable top-right and disable it. While the
subjective quality of disable top-right modes is greatly down. I guess there
are some bugs on calculation of PSNR in x264, Is there any bug feedback on
this issue?
