I wasn't very clear, either.  I tried three ESCs in a row, and all I
got was "ESC ESC" in the minibuffer, and the third one cleared it.

Perhaps your window manager is watching for three ESCs in a row, and
killing whatever window that sequence occurs in?  Sounds unlikely, I
know, but since "emacs -Q" fails, the problem most likely lies
elsewhere.  You might want to check your WM/DE settings to see if
there's a triple-ESC keyboard shortcut somewhere.
