What that merge request does is forcibly enable "hint metrics" when the display scale factor is 1, and forcibly disables "hint metrics" at all other scale factors. Presumably that indirectly disables/enables subpixel positioning as well? I don't know. There is no subpixel positioning setting.

I also don't know what "hint metrics" are or how this setting interacts with the separate "hint style" setting.
