[Octave-bug-tracker] [bug #53073] OpenGL color LUT seems incorrect after a print() for the Qt graphics toolkit

[Rik]

Follow-up Comment #2, bug #53073 (project octave):

LUT usually stands for Look Up Table.

@Dan: Could you create at even clearer example.  This might work.


close all
graphics_toolkit qt
hp = patch ('facecolor', 'm');
# Record screen capture of just Qt plot window
print test.pdf
# Record screen capture of just Qt plot window


We should be able to use a color picker to get the exact RGB values and see
what sort of difference there is.

Also, does something like refresh() work to change the color back?  Or is it
only a command or movement (such as window resizing) that causes the correct
color to return?

If you use software rendering rather than Nvidia, do you still see the same
result?
