Hi All,
In a transparent NSOpenGLView (I mean one can see the views that are
behind it in the window)
I draw a texture that has some zone with an alpha value different
from 1.
If the alpha value is 0 everything is OK and I see the background
If the alpha value A is such that 0 < A < 1 then it blends directly
with what is behind the view.
If I turn off the transparency of the view, everything is drawn
perfectly.
Does any one knows what this problem comes from?
Regards
