[Octave-bug-tracker] [bug #44776] [Qt] Maximizing a figure does not trigger a repaint event for its content

[Dan Sebald]

Follow-up Comment #3, bug #44776 (project octave):

It's hard to tell, but it seems the figure may be redrawing but with the
incorrect size window size.  The first time I tried maximizing the figure size
was correct.  But I then minimized and the figure was still appeared too big
as in your example screenshot.  Maximizing then made a figure that was too
small.

It's as if the redraw is using the one-previous window size and randomly
sometimes the current window size.  This behavior would not be noticeable when
dragging the window size slowly because if the window size is off one or two
pixel there's not much difference in size.  Comment #2 suggests the same
thing: fast-drag is more noticeable.

There could be a race condition between the drawing of the figure and the
update of the window size.
