Window minimizing animation leaves decoration trail on screen

[Hernando Torque]

TEST CASE:
1. Maximize any application (e.g. Nautilus) which launcher icon is not one of the first few items.
2. Minimize the window.

RESULT:
The window decoration leaves a trail on the screen (see screenshot).

This happens on two systems (Intel; Intel and Nvidia with nouveau and BLOB).
