clipboard and @ not working on linux

[Psykedelius]

Hi,
I was trying to export my application that needs a login email and a password.
My application starts, the login screens appears and i can't find a way to type the "@"
of my email address, and i can't copy/past it too.
The Linux virtual keyboard don't do the job neither.

I use the latest Kubuntu.

PS: if you have any tips to help i would be glad !

Make a @ Button and add the Text "@" to your Textbox
