38.2: "Increase map resolution" is absolutely ineffective for raster maps. Doesn't matter if "Select map resolution automatically" is on or off. Also, the map resolution increment in all my presets was reset to 100%. Not that bad, as I have to find new best values with the new system anyway, but still...
Apart from that bug: I know it's more complicated, but all the problems with "Increase map resolution", especially for raster maps everyone seems to be having, I think the only feasible solution is to make this a property of the map. It's obvious that different raster maps look best in different zooms/resolutions.
It's nice and well that Locus choses the base resolution based on dpi, but then the user has to have the ability to adjust this according to reality and personal tastes.
I would propose that every map gets a "Resolution adjustment factor" from, say 25% to 500%. At least all offline maps. Then there's still the general "Increase map resolution" in settings/presets which allows to adjust resolution based on activity (e.g. biking needs more zoom because I look at it from further away).
What do you think, too difficult?
