Or, you know, don't do any of those silly dances and just let the windows stay where they are the whole time between turning the displays off and on?
Reminds me of that problem with video driver update on Windows when the screen is momentarily resized down to 1024x768 resolution and then instantly goes back to 2560x1440: all the non-maxed windows get shrunk down and shifted to the upper-left corner (so they would be visible on a 1024x768 screen) and then they just stay like this. It's totally useless and actually quite annoying.
