I'll comply to Ubuntu's bug procedure(s).
Yet, I think it is important from a developers point of view to know from the start that this issue is not related to a specify HW, but rather a more general problem (i.e. at least concerning the Z77 desktop, the X230 laptop and the Z87 desktop).
Unfortunately, it is not possible to add multiple files to a single comment.
