Under wayland, devicePixelRatio can't get non-integer multiples of dpi.

Under wayland, devicePixelRatio can't get non-integer multiples of dpi, for example, I set the system's scaling factor to 1.25, but the wayland protocol reads wl_out_scale as 2, which is incorrect. https://doc.qt.io/qt-6/highdpi.html The documentation clearly says that QScreen scales to integers under wayland, does that mean that currently qt6.8 can't handle non-integer dpi?
