I have a debian box running latest kde plasma 5.12.4 ; I connect to the box using vnc from my macbook and I use an external usb 105keys keyboard. Under macos the numpad works correctly but on plasma apps, like konsole or kate, i'm not able to type numbers, it is as if the "numlock" is never on. Using gtk applications like gnome-terminal and gedit, the numpad types numbers, as expected.

I tried the following : forcing "on" the numlock in plasma system settings, disabling global shortcuts on the specific application, but nothing changed.

It looks like a plasma only problem, any suggestion ?

thanks
