the bug has not been patched yet, it would require the Samyang lens station for fuij which is about £59 but useless atm as there is no files available. I doubt that fuji would patch this issue for Samyang.
I've heard that it's only on the x-s10, but fine on the xt4. I can't find any new info about it. It's not clear how you would even update the firmware if they do a update.
