| I have no experience with Gnome and KDE, but certainly both scaling and fractional scaling cannot give anything else than bad results. For correct text rendering, you must set the screen to its native resolution and then set a correct value for the DPI so that a font of 12 points (or of 10 points, whichever you prefer) should have the right size that you like in a default font. If you use Gnome or KDE, I do not know where they can set the exact value for the screen DPI, but they must have such a setting, otherwise it is indeed not possible to use properly a HiDPI display. EDIT: At least KDE has a "Force Font DPI" setting, while the corresponding setting in Gnome seems harder to find. It appears that the reason while I never had any problems with bad text rendering on HiDPI in Linux is that I never attempted to use the so-called HiDPI support from Gnome and KDE, which is just an extremely ugly and inefficient workaround for GUI applications that have been written incompetently, so they lack the options for changing the sizes of fonts and of other GUI elements. In my experience, most Linux applications have the required options, so they do not need the "HiDPI support" workaround, which is guaranteed to render badly any text. |
