I think instances of 'Qredisplay_dont_pause' are still present in the
codebase so some build configurations are now broken (at least my
GNU/Linux one).

Could you have a look?

Thanks, should be fixed now.

Thanks. That one should be fixed now. The joy of having n!
configurations.

This one I don't see here, with clang 19. And I must admit I don't
understand it what it is complaining about. The function root_frame
is pretty simple:

  struct frame *
  root_frame (struct frame *f)
  {
    while (FRAME_PARENT_FRAME (f))
      f = FRAME_PARENT_FRAME (f);
    return f;
  }

and FRAME_PARENT_FFAME is

  INLINE struct frame *
  FRAME_PARENT_FRAME (struct frame *f)
  {
    return NILP (f->parent_frame) ? NULL : XFRAME (f->parent_frame);
  }

Any idea?

I think it wants to tell you that the argument F of FRAME_PARENT_FRAME
could be NULL.

The only explanation I can find is that GCC seems this

  #define SELECTED_FRAME()				\
       ((FRAMEP (selected_frame)				\
         && FRAME_LIVE_P (XFRAME (selected_frame)))	\
        ? XFRAME (selected_frame)				\
        : (emacs_abort (), (struct frame *) 0))

and doesn't realize that it actually never returns NULL. That's from up
the stack in is_cursor_obscured.

Beats me, sorry.
