    Phoronix: KDE Now Supports Fractional Scaling On Wayland

    While KDE's new goals will include focusing on Wayland support, a big TODO item was just crossed off the list this week... KDE Plasma finally supports fractional scaling under Wayland...

    Known and documented bug with QT, this happens even on QT applications on MacOS, so no, it's not KDE related.

    Actually i've test fractal scaling on Qt 5.13.1 all artifacts are gone, so you should wait for it.

    So we talk about different bugs, i told exactly to fractal scale on X11, it affect all Qt apps, not only KDE, it's horizontal / vertical over widgets. I don't see it, it's quite easy to every application with different dpi `QT_SCALE_FACTOR=1.5 kwrite`

    Fan or contributor, my point still stands. You continue to defend KDE without understanding the facts: This bug affects KDE apps that use the KTextEditor framework. Not all qt5 apps are affected, but KDE apps that use KTextEditor are affected. Yes, it could be an issue with Qt, but it could also be an issue with the way KTextEditor calls Qt.

    Since the KDE devs have not filed a bug report upstream, I’m inclined to believe it’s on their end. The Qt bug report you linked to is from an end user. You know perfectly well that it will never be touched as it's completely lacking any of the details needed for Qt devs to work on it.

    So i'm a contributor to KDE, not a fanboy, if i can fix i'll do, but i don't have deep knowledge in rendering engine. Whatever, rendering is something that KDE does not do, it's done in Qt / Graphic stack, that bug is totally unrelated to KDE since you can see horizontal / vertical artifacts on drawing lines which means rendering do wrong calculations when it draws. Meanwhile bug report has exactly same artifacts and they are caused by Qt itself, despite bug is assigned or not it's in Qt / Graphic stack.

    Swing and miss. Your qt 5.6 bug report was not confirmed, has to do with widget scaling, has no steps to reproduce, or any technical information. It will never be addressed nor is it related to KDE's current problems.

    The issue I am referring to affects KDE apps that use KTextEditor framework. If KDE devs actually believed that this was an issue with upstream qt, then they would to file a proper bug report. In the meantime, all of the evidence points to an internal KDE issue with their framework. All the fanboyism in the world won't change those facts.

    Oh really? What Qt bug is it?

    It’s a Qt bug of some kind. I ran into it myself, and it made my laptop unusable. On the positive side, it does not occur under wayland, on the negative side, wayland itself had issues under KDE last time I tried it.
