B2Qt demolauncher WLAN passphrase input field hidden by virtual keyboard

On Raspberry Pi, the WLAN password input field is hidden when typing it in with Virtual Keyboard and one cannot see what one is typing, or is one typing at all. It is not clear what one needs to do after typing to make the Connect to network ('SET') button visible.

While at it, it is worth looking in to also other hardwares as well as other possible manually writeable fields withing Raspberry Pi.
