Created attachment 128604 [details] Screenshot of main window with squished tree view. SUMMARY On a HiDPI screen, the line height in the list of calendars widget in the main view is too low, making the lines squished and hard to read. STEPS TO REPRODUCE 1. Launch KOrganizer on HiDPI screen (see parameters below) with several calendars enabled OBSERVED RESULT Tree view that shows calendars in main window is vertically squished. EXPECTED RESULT Tree view with same line spacing as everywhere else in the program. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 19.10 (available in About System) KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.67.0 Qt Version: 5.12.4 ADDITIONAL INFORMATION: The display is a Thinkpad X1 display, 2560x1440 resolution, under X11R6. KDE display settings: native resolution, global scaling 100%, Force font DPI off. Xft.dpi: 192 QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCREEN_SCALE_FACTORS=eDP-1=1;DP-1=1;HDMI-1=1;DP-2=1;HDMI-2=1;
For what it's worth, I upgraded to 5.14.1 (20.04.0) with Plasma 5.19 and Qt 5.15 on OpenSUSE Tumbleweed and the problem is gone. I had to change a number of HiDPI settings - Global Scaling 200% in particular - and so I can't say whether it's the KOrganizer update or the subtle differences in HiDPI handling between Plasma versions and distros.
