First of all, sorry for my bad english.
I´m begginer in OpenGl. I use Tao Framework to have a control where draw.
In my application i draw signal_1, clear control with Gl.glClear(Gl.GL_COLOR_BUFFER_BIT | Gl.GL_DEPTH_BUFFER_BIT), and the paint signal_2.
But when i move over the form of the control another window, signal_2 disappear and signal_1 appear.if i move the window over the opengl control slowly signal_2 and signal_1 alternate.
i forget clear other buffer?
My opengl initialization:
Gl.glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
Thanks in advance.
