I recently updated to KDE 4.10. Now when I minimize windows, the task manager shows them being black and white. I find this very annoying since I tend to find windows primarily based on colors, not based on the shape of their icon. It takes me usually at least twice as long to find the window I'm looking for now because of this. Is there any way to switch it back to previous behavior where minimized windows would still have color in the task manager?

This is what it looks like now. Firefox is minimized while the System settings window is not. It's usually quite easy to spot a bright orange and blue icon. Not so here:
