windows show entirely white or black when user interrupts minimize animation on nvidia

Steps to reproduce:

1) Open window of any kind
2) Minimize window by clicking on the minimize-button
3) Quickly click on the corresponding launcher icon to bring the window to the foreground again

Expected result:

Window shows up as one would expect.

Actual result:

Window comes back, but often either entirely white or black.

I attached a video that shows this "problem". Note that the bug occurred on both the drivers from nvidia-current-updates as well as nvidia-experimental-304.
