Redraw after windows sleep

We recently moved from SDL to SDL2 and have found that after Windows goes to sleep and wakes up, the SDL2 screen is not automatically refreshed.
Our application only updates the screen when there is a change, and only the parts of the screen that needs a change is redrawn.
Can we do anything to get SDL2 to refresh its framebuffer on the screen after windows sleeps?
