D24373: [KCM] Limit scale factor increment to 6.25% on X11
cullmann added a comment. On Wayland one seems to always scale up to the next full factor (e.g. 2) and then scale down the rendered stuff via gl to the selected factor (e.g 1.5). That leads to other issues but doesn't let rounding stuff creep into the rendering via Qt. For non IEEE stuff: perhaps that will be available in the future, but at the moment all really available RISC-V ISAs provide just IEEE, too. And staying in some 1/(2^x) range won't hurt any alternative approach I assume.

MayeulC added a comment. @cullmann from what I understand, it is related to what you wrote in https://cullmann.io/posts/kde-qt-highdpi-scaling/ ? How is it only related to X11? Just a small note: we will probably see some platform that do not use IEEE 754 floating points appear in the next years (unums like posit are well positioned to make an entry on the market, together with RISC-V CPUs). Those will have different tradeofs.
