SUMMARY
I e.g. am opening konsole windows via hotkey (left-windows + t). If you open two windows and wait a second after opening the first one, the windows are placed fine side by side by the smart window placement logic. But if you quickly press the hotkey twice the windows are positioned at the same position. So the first window is completely covered by the second window. It would be much smarter if they still would be placed side by side.

STEPS TO REPRODUCE
1. enable smart window placement
2. configure a hotkey for opening an application (like konsole or dolphin)
3. press the hotkey quickly two times

OBSERVED RESULT
The two windows are placed at the same position. The first window completely disappears behind the second window.

EXPECTED RESULT
The two windows should be placed side by side as they are opened when pressing the hotkey with a short delay of e.g. 1 second.
