In the change log for 1.14.3 it was stated "Fixed: too big undersize for mkv", and I've had great success with 1.14.3 with almost exact or marginally under. There is no mention of any changes in 1.14.4 around this area, but 3 encodes out of 3 are larger than 1.14.3 using exact same settings (fixed size of x, 2-pass, same profile etc). The only difference would be the version of x264 (I was previously using x264 0.72.1240 35627b6 with 1.14.3) and 1.14.4 now uses x264 0.75.1251M e553a4c.
Would that explain it, or is there anything else people can think of ? (of course I will re-test with the same release of x264, I'm just asking in case there is a generic issue in 1.14.4).
