Here is an explanation of fractional scaling of GNOME in Wayland which is what the parent is using at 125%: https://discourse.gnome.org/t/how-fractional-scaling-works-in-wayland/5373 https://discourse.gnome.org/t/how-fractional-scaling-works-i... For scaling 125%, the client windows are rendered at 2x their size and sampled down. On the parent's system, a full-screen window would be rendered at 6144x3456 and scaled down to 3840x2160 (0.625%). This gives a blurry result and is taxing on the graphics chip. Qt apps and Firefox support scaling themselves which gives a much crisper result for fonts and line-art.
