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

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?
