Hence my proposal of even using 18x6. 17x5 might even be tested
(except for 4:2:0 sampling, but chroma should be affected).

However, with CPUFLAGS=none, fate isn't able to produce reproducible
results for a height of 142, ie:
1) running once the first fiew tests (amv,asv1,asv2)
2) copying ./tests/data/fate/vsynth3-* to $(BASEPATH)/tests/ref/vsynth/
3) re-running the same tests
will result in an error every time

Change height to 144, and it works. Interlaced tests may bring another
class of issues I guess in that case.

To test that yourself, you can apply the attached, updated, patch and
modify FATEW/FATEWH in $(BASEPATH)/tests/Makefile to your liking.
