The mouse pointer is controlled by X so this shows nothing.

Yes, it interrupts whatever Emacs is doing.

This is a released version.  It works for me and there haven't been other
reports so there must be something unusual about your set up.  It may be that
there are just too many completions for Emacs to handle.  What happens if you
do the same on the command line?  Do you get something like:

(gdb) b <TAB>
Display all 20954 possibilities? (y or n)

If not then could you send details of the gdb command and program that you are
using.  Does it happen with a simple "hello world" program?
