I'm not seeing that on Linux.  The window size seems to work fine, as 
far as I can tell.  The information is being sent.  Is some kind of 
strange combination of switching between windows and sizes?  The 
following does seem some somewhat suspect:

	// Set plot size
	if (qt_setSize)
	{
		term->xmax = qt_oversampling*qt_setWidth;
		term->ymax = qt_oversampling*qt_setHeight;
		qt_setSize = false;
	}

If 'size' is set in the options then the term structure is updated and 
setSize cleared.  But what if one then just switches the term number?

set term qt 4
plot x
set term qt 5 size 300,300
plot x**2
set term qt 4
plot x

I just confirmed that doesn't work properly.  Is that what you are 
referring to?  Intermixing that qt_setSize test with the streams sent to 
the outboard program might fix that size-persistence issue, i.e., the 
size command doesn't get sent unless the user actually specified the size.

	qt->out << GESetCtrl << qt_optionCtrl;
	if (qt_setSize)
	{
		term->xmax = qt_oversampling*qt_setWidth;
		term->ymax = qt_oversampling*qt_setHeight;
		// Set plot size
		qt->out << GESetWidgetSize << QSize(term->xmax, 
term->ymax)/qt_oversampling;
		// Initialize the scene
		qt->out << GESetSceneSize << QSize(term->xmax, 
term->ymax)/qt_oversampling;
		qt_setSize = false;
	}
	qt->out << GEClear;

I tried something like that and it doesn't work exactly right either. 
I'll have to look at that later.

BTW, I also notice that the maximum size is kind of small.  Try

set term qt 6 size 800,800
plot x

and it doesn't look any larger than the default plot size.  Going 
smaller works though:

set term qt 5 size 300,300
plot x**2

Another BTW, the mouse scroll wheel button (center button) seems a 
little odd.  Using that in one Qt window causes plot activity, but it 
also cause plot activity in another Qt plot window that is open.
