Questions tagged [double-buffering]

A computer-graphics technique for updating a dynamic image that greatly reduces the visual artifacts, especially flicker, caused by the screen pixel being changed. The new image is drawn in a "hidden" buffer while the user still sees the old image, stored in a "visible" buffer (hence "double-buffering"). When the new image is fully drawn, the visible and the hidden buffers are switched very quickly and the hidden buffer content becomes visible.

Why does double buffering cause more lag and flickering when resizing the window, using OpenGL and SDL?

I'm using OpenGL and SDL to scale a software-rendered framebuffer of a fixed size (320x240) to the client window size while maintaining the ratio by putting black bars on each side if necessary. When I use single buffering, the rendering is smooth…
