Diff produces a broken table
Diff'ing these two files produces a broken film grain table. The coefficients are b0rked somehow, and if you use the table in aomenc, you get a very interesting grain layer there..

The same happens if you use the original source (1080p) and crop the left and right side borders (244 pixels both) off and try working on that without downscaling to 720p. If you crop and add the borders back before encoding the reference and lossless clip, no problems so the problem is somewhere in grav1synth.
I also tried various cropping parameters but none of them worked. Cropping the top and bottom borders has not caused any problems in my tests.
Looks like widths 1920 and 1280 work. Others have issues, didn't test higher ones yet.
Some tests with various widths: 3840 ok 3600 not ok 3584 ok 2960 not ok 2880 not ok 2560 ok 1920 ok 1480 ok 1460 not ok 1456 not ok 1280 ok
