I installed octave-4.4.1-w64-installer.exe on my Windows 10 1803 x64 box, and
some plots that worked fine in 4.4.0 are now not working. I am using the qt
When I do a plot of a very large array, some of the graphic elements are not
visible. For example, if I do
there is nothing shown in my plot at all when the plot window first opens.
However, if I maximize the plot window (and click Autoscale), then the
expected horizontal line appears, although it is paler than the normal plot
color. With a larger array, like length 1000000, even maximizing the window
doesn't show anything.
If I rename the opengl32.dll file in octave's bin folder, then this problem
goes away. So this is not a showstopper for me.
As another data point, if I do
then with the plot window at the default size, the top and bottom of the sine
wave don't show up, although the rest of the wave does (see attached
screenshot). If I maximize the plot window, then the entire wave is visible.
Not sure what other info might be relevant, but I am happy to provide more or
do other tests if it would help.
