Previously, fractional scaling was detected but set an integer buffer scale which the compositor would down-scale causing blurry output. Now the fractional scaling interface is used when available to set the DPI and set the internal buffers size & viewport transformation to ensure 1:1 pixels from Blender to the Wayland output. Tested to work with multiple monitors with mixed fractional/non-fractional scale. Note that this change causes a regression for when fractional scaling is set on a compositor without support for fractional-scale-v1. Supporting fractional scaling in both cases is possible but overly complicated. This case already wasn't working so well - with blurry output due to image scaling, now the DPI wont be accurate in this case although Blender is still usable.
