Comment 3 for bug 1220231

I think this is the same problem, if not I'll open another bug report:

Slingshot`s layout resets to default after resolution changes.

I had set it to 8x4, which fit nicely on about 1/3rd of my 1920x1080 screen, but when I played an old game (through WINE) the screen resolution was temporarily set to 1024x768. After closing the game, my screen resolution returned to normal but Slingshot went all the way back to 5x3.
