I have a problem. I have created a routing to copy an image to the front and the back buffer. I display it. I use it as a loading screen. I also created a loading bar. Simply overwrite a portion of the image.
I works well, except one thing. During the loading process the screen flashes. The picture is erased somehow. But I do not clear the buffers.
The main problem is that I must do it in this way. So the create textures from that picture and produce quads to cover my screen is not usable for me.
Does anyone has an idea?
