Masked password form by internet banking

Today I tried to log in into internet bank account of my company. The password on a login page is secured against keyloggers so that an user doesn't provide a full password. Only every second/third letter is required. The problem is either with a browser or OnScreenKeyboard. (i bought a tablet not a netbook so i'm not gonna buy a hardware keyboard for my M10). The form for a password contains of a few empty spaces that have to be filled eiter with a digit or a letter. Ubuntu tablet fills two or three empty spaces after clicking only one letter.

Here is how to observe this problem when we have the tablet in a horizontal position (this site recognizes the position of the tablet, displaying the page either for pc or mobile devices so do not put the tablet vertically cause the login page will look differently):

1.go to https://m.bzwbk24.pl/centrum24-mobile-web/login
You can switch to English if You like. There is a link.
2. Give a NIK (login number) for example: 92147354 and click the red button "Dalej" or "next"
3. Try to fill in the empty spaces

Only one letter should be given after one click.
What we observe at the moment is that after one click, our entry will be multiply.

One more tip:
We notice the same behaviour while writing an e-mail message with the YahooMailapp that probably uses some web browser interface. When we are done with writing our message and want to click sent, provide a subject or an email adress, the last word or a sentence will be written again.
For example i write:

Best regards

Marcin

Now i click send or click the subject/email address window and my name will be send as"MarcinMarcin"
