I dont use asahi but it seems like it uses kde plasma? In that case you can use qt/kde specific scaling which supports per monitor fractional scaling. Set:
PLASMA_USE_QT_SCALING=1
QT_ENABLE_HIGHDPI_SCALING=1
QT_SCREEN_SCALE_FACTORS="1.5"
environment variables. Note that QT_SCREEN_SCALE_FACTORS works with multiple monitors, for example: QT_SCREEN_SCALE_FACTORS="1.5;2" to set first monitor scale to 1.5 and second monitor scale to 2.
For a scaling option that works in other gui frameworks you can modify ~/.Xresources and add: Xft.dpi: 144
which sets scaling to 1.5 (96 * 1.5 = 144).
Note that gtk applications dont support fractional scaling on x11 and neither do they on wayland. Some wayland compositors just set gtk application scaling to an integer value and then downscale the window, which makes it blurry, makes it run slower and uses more power (battery on laptops).
