As many have mentioned, there is not quite enough memory for a full palette offscreen buffer on the Fenix 6x...this is a considerable hurdle for people that want to use stock fonts which are anti-aliased and have partial updates for always on second hands. I know you can reuse the buffer in sections, but that can be non-ideal when the second hand sweeps by the transition point, plus it increases the size and complicates the code required to line things up. Using a palette and custom fonts that are not anti-aliased obviously solves this and works for one language, but to support all character sets this becomes problematic as well.
Making watch faces that don’t support the newest model is a bad plan all around, as is limiting the option for partial updates on them, and/or limiting the supported languages. If there was even 128K available, that should be enough. Anyone from Connect IQ know if this is in the works? Thanks.
