           Summary: EDITING: slow to insert Text Box

           Version: 5.4.0.0.alpha0+
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

          Severity: normal
          Priority: medium

bibisect details

Working on debian-stretch in the daily Linux dbgutil bibisect
repository, I see an increase in the time to process the menu option
Insert > "Text Box".

In non-dbgutil builds, the times will of course be shorter.  It would
be interesting to know if they are in proportion.  It may be that a
non-dbgutil build is fast enough that even the slowed-down response is
not worth fixing.

For testing, It will be convenient to have (in Linux) 
`top -d 1 -p $( soffice.bin )` running in a window so that you can see
the accumulated CPU time.  I am reporting CPU times just because it is
easier to watch them than changes in the Writer window.

STR
---
(1) Open new Writer document.
(2) Highlight menu option Insert > "Text Box".
(3) Note accumulated CPU time.
(4) Take menu option.
(5) Wait for accumulated CPU time to stabilize and note the value.
(6) Calculate the incremental CPU time from the values noted in
    steps (3) and (5).
        Expected : about 1 second
        Observed : about 12 seconds

For comparison, Impress in version 2017-04-28 responds to Insert >
"Text Box" in 0.18 CPU seconds.
