I installed it on two different occasions. Theming was broken both times. What's wrong? Missing recommended packages? No, I found the answer on the forum.
You need to modify /etc/X11/Xsession.d/98qtconfig so that KDE isn't affected by Qt theming in Xfce.
Forum user baldyeti has provided a modified 98qtconfig that will not modify Xfce, but allow independence for KDE and LXQt. Your 98qtconfig should look like this:
Code: Select all
case "$XDG_CURRENT_DESKTOP" in KDE|LXQt) ;; # no-op *) export QT_QPA_PLATFORMTHEME=gtk2 export QT_PLATFORMTHEME=gtk2 export QT_PLATFORM_PLUGIN=gtk2 ;; esac
This has been tested with KDE and it will give you working themes and icons. If you still have graphical problems you can go to Settings > Display > Compositor and try some things:
1. Enable compositor at start-up
2. Set Vsync to Never
3. Uncheck "Allow programs to disable compositor" (this gave me working compositor)
