Follow-up Comment #4, bug #45604 (project octave):
Well, I'm not so sure what the issue without digging into things deeper. (I'm
reluctant to look into the Qt terminal because last I saw it uses the callback
strategy, which I view as a structural issue. Also, to really pinpoint driver
issues means compiling a lot of local utilities, which I've done for another
problem, but it's a lot of work.)
If the person reporting the bug could verify it is all of the graphics
toolkits failing that would help narrow things. Otherwise, if it is only Qt,
it might be that this bug and https://savannah.gnu.org/bugs/?45540 are the
same.
One comment on the slowness of the drawing. I think the reason this is so
slow is that the construct,
x=1000
y=1:1000
plot(x,y)
creates one thousand individual curves (all consisting of a single data point)
on the plot. Each of those curves is an object so it must have a set of
properties created and initialized. Perhaps that is the slow part. Maybe
that code should be optimized internally.
