This is a workaround to enable dark theme in KDE Fedora Linux.
My system info:
Operating System: Fedora Linux 38
KDE Plasma Version: 5.27.6
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
Kernel Version: 6.4.11-200.fc38.x86_64 (64-bit)
Graphics Platform: Wayland
Of course you will need to run wireshark as root, so the theme settings for your current user will not apply for the root user. All you need to do is logout from your current user and login again as root, then change the theme settings for the root user to dark. Logout and login again to your normal user and you will find that the app now has the dark theme.
Which operating system (linux, Windows, Mac) are you running Wireshark on and which Wireshark version?
(adding output of
wireshark -v
orHelp->About Wireshark
will show both of these and more)
