Thanks Robert and Paul. I just assumed that a direct GDI call would be
faster, but when I think about it, that can't be true (assuming a
decent OpenGL driver).
I did as you suggested and it works very well. Mostly.
If I resize the window and make it wide and short, my background

I'm confused about the code that does the resize in GraphicsContext.cpp
(part is pasted below).
In my case, my background camera is a slave camera with an absolute
reference frame.
So, it isn't going to be caught in the if statement on line 7 and will
fall through to the else. In this block,
I changed the if statement on line 7 into a nested if and now things
are working for me. I changed lines 7-9 to:
if (slave)
{
if (camera-getReferenceFrame()==osg::Transform::RELATIVE_RF)
{
switch(view-getCamera()-getProjectionResizePolicy())
and now everything is working correctly
Hi Cory,
OpenGL calls used to fill a background colour will be the faster way
to accomplish a gradient background and it'll be a portable solution.
Robert.
