I can confirm this is sometimes happening, but I don't have any example ready at the moment.

Also, a similar thing is happening with volume up/down indicators. Many games react to them as focus lost event. So some games stop playing any sounds/music for a split second (because they are programmed to stop playing sound when "minimized"), and some games even minimize automatically when I press volume up/down multimedia keys. The game window then simply disappears and I can only see it the gnome overview, which is very confusing and annoying (when this happens each time you want to adjust the volume).

If you want a simple reproducer, download Cannon Brawl Demo [1] (free) from Steam and press volume up and down multimedia keys while being in the main menu. The game window will often vanish. After debugging this for a while, it seems the "focus out" event is not sent during a single quick press of volume up/down, but if you hold the volume key for a bit longer (to increase/decrease the volume more quickly), it triggers the bug.

Maybe the Super+Space focus problem is similar to the volume change issues?
