There were early online grumblings about AF issues when X-H2/T5 released across online site/forums. Fans quickly swarmed in countering with it works amazing for them etc...

Jerred Z made video showing the AF issues he encountered. He used eye AF af-c with "release priority" (default). Changing to "focus priority" would be better as many comment. However, his response was his sony/canon works perfectly fine with "release priority" and shouldn't need to switch.

Later Omar Gonzalez showed people that AF+MF needs to be turned off as warned in the manual which many would over look.

I'm sure there will be more AF quirks and best settings yet to be discovered. Sit tight, wait, let the early adopter/guineapig figure it out and/or maybe Fuji will address it via firmware before then. If not there is always X-T6/H3 or go Sony/Canon. IMO, this AI AF stuff Fuji added is new tech and plenty of improvements will be made.

My hunch is the processor in the X-T5/H2 isn't quite fast enough to handle some AF situation to perfection at 40MP. AF-S is fine, but AF-C had some issues. X-H2s seems fine since it is only 26MP? Might be one reason why Fuji decided to refresh the EVF of the AF box position less. Maybe algorithm is inefficient or needs tweaking. Shrugs. Sony BIONZ processor was already speedy handling eye AF better than prior Fuji. When they added AI AF chip to A7RV and the processor got upgraded to be 8x faster.
