These are 64 bit (amd64) images, based on Debian stretch and KDE plasma 5.
Workstation KDE start menu is totally broken for a yet to be discovered reason. One can right click on sdwdate-gui, click open log, right click the in the console window, click “show menu bar”, and open a new terminal to investigate or otherwise play around.
Since it is broken on the workstation only, not on the gateway, it is
most likely caused by something that Whonix does. Newer packages from
Debian would probably not solve it.
