I meant that you can get feedback about when a frame was presented to the screen so you can sync with the display refresh. See https://github.com/glfw/glfw/issues/1350#issuecomment-447534605. X11 has a similar extension called PresentCompleteNotify (see https://stackoverflow.com/questions/48424320/precision-timing-of-gdk3-gtk3-window-update)
