[Gnuplot-bugs] Mouse behavior change 5.2.8 -> 5.4.2 with term = x11

[Glenn G. <gd...@zp...>]

Greetings gnuplotters,

This question was posted to gnuplot-info about a week ago, but received no
response, so re-submitting here as a bug report.

Thanks,

Glenn Golden

=========================================================================
Platform:           Arch linux, x86-64
Gnuplot versions:   gnuplot-5.2.8-2,  gnuplot-5.4.2-1 (both from Arch repo)
Gnuplot terminal:   x11

Minimal example:

   gnuplot> set term x11
   gnuplot> plot sin(x)
   gnuplot> unset mouse	

In 5.2.8, "unset mouse" entirely eliminates the mouse coordinate display
region at the bottom of the plot window, and the window then resizes
slightly (reduced height) to 'shrink wrap' the remaining plot area.

In 5.4.2, "unset mouse" only freezes the coordinate display, but the display
region itself remains visible within the plot window (showing the last set
of coordinates, frozen) and no resizing of the plot window occurs.

I went thru the various mouse options in 5.4.2 to see if perhaps there
might have been an option added since 5.2.8 that toggled this behavior,
but no joy.  Unable to find any option combo that restores the old long-
standing behavior, but perhaps I missed it.

Can anyone reproduce this?  If so, is there some option or other trick
that can be used in 5.4.2 that will restore the old behavior?

If it's not possible to somehow restore the old behavior with 5.4.2, then
please consider this as a bug report (regression against 5.2.8). I am also
pretty sure (but cannot easily verify) that the old behavior extended back
to at least 4.6.6.

Thanks to all for maintaining gnuplot.
