Scale would be rounded up , that means 1.25 => 2, 3.25 => 4. Under X, the application will have to down scale while painting the thumbnails. Under Wayland, with fractional scaling, application paint at the scale ceil up,(1.25=> 2) and the fact that the scale factor is not an integer is non of their concern, the compositor downscales on the GPU the application then. -- Méven
