This week in KDE: Better HiDPI on X11

Filed under

We made a big improvement to Plasma’s high DPI support on X11 this week! Beyond that, there’s a lot more cool stuff in progress that hasn’t been merged yet; look for that stuff next week and beyond.


The buttons that appear when you hover your cursor over entries in the Clipboard applet are no longer sometimes mis-positioned (Eugene Popov, Plasma 5.22.4)

A System Tray popup that has been pinned open no longer closes unexpectedly when you open its configuration page (David Redondo, Plasma 5.22.4)

Plasma Panels once again use the correct edge-specific theme graphics, when present (Obno Sim, Plasma 5.22.5)

In the Plasma Wayland session, System Settings’ Shortcuts page no longer lists three “KWin” items; they now all have proper names (David Redondo, Plasma 5.23)

When using a high DPI scale factor on X11 with the default Plasma scaling system (instead of native Qt scaling, which is used on Wayland and when manually setting PLASMA_USE_QT_SCALING=1), large Task Manager icons, System Tray icons and ToolButton icons all over the place are now displayed with the correct size! (me: Nate Graham, Frameworks 5.85). This is not the end; other things are still too small, but I am working on those too.

KDE's HiDPI Scaling Support For X11 Is Getting Into Better Shape

  • KDE's HiDPI Scaling Support For X11 Is Getting Into Better Shape

    While KDE on Wayland has generally enjoyed good HiDPI support, it's now taken until 2021 for KDE's X11 HiDPI support to be in a position of greater usability after evolving over the years.

    With KDE Frameworks 5.85, when using a high DPI scaling factor on X11 with the default Plasma scaling system, task manager icons, system tray icons, and tool button icons are now displayed the correct size. But this isn't "the end" as there still are issues being tackled with some elements being too small and the like. At least more of the KDE desktop is behaving correctly under X11 with the HiDPI scale factor.
