[Octave-bug-tracker] [bug #51829] Consecutive plots gradually drifts out of figure area

[Dan Sebald]

Follow-up Comment #1, bug #51829 (project octave):

Which toolkit are you using?  I'm not quite seeing what you are seeing.  (I'm
using the latest development code on Linux.)

For FLTK/Qt/gnuplot the image doesn't keep growing in side with each
iteration, but the FLTK plot has the Xlabel extending past the bottom of the
figure.  Qt lays things out nicely.  gnuplot is pretty good, but it has a
separate problem of the Ylabel overlapping the tick text (that's a separate
issue from this bug report).

Both FLTK and Qt have the annoying trait of the figure window and plot growing
in size about 10% and then shrinking back to the original size with each
iteration.  Looks awful.  In fact, there's a good chance that could be the
source of error on your system.  I.e., with each iteration this 10% growth and
subsequent shrink could be incrementally increasing some variable that keep
track of plot size due to some poorly synchronized cross-thread action--as you
point out the need for a pause.  Wild theory, but that might be where to look
first.

Or font size.  Is that first line changing the font size necessary to make
this behavior happen?
