- Creating a new frame with 'C-x 5 2'. The result is a responsive frame,
    all the while the previous one is in that weird state.

This bit almost certainly means that it's not an Emacs problem, but
something related to the other software on your system.

That's possible, actually. I've had another program (a terminal emulator) show similar behavior. I'm using a somewhat outdated desktop environment (Unity 7), so there might be some bugs in its windowing code. A reboot usually solves the problem for a while.

display engine updates all the frames one after the other, in a single
thread, so the situation where one frame is updated, but another
isn't, is simply impossible, as far as the Emacs code is concerned.

Having said the above, surely there is also some code that passes the rendered frame contents to the windowing system, or the graphical toolkit?

Did you try looking at your system's logs for the times when these
freezes happen?  Or search the Internet for similar reports, not
necessarily related to Emacs?

I will try, thank you.
