All animations disabled, but top-right corner buttons still animated?

Hello. There's a small bug in Windows 7 that's caught my eye a long time ago.

It's about the Minimize / Maximize / Close buttons. I've disabled all animations in Performance Options, but they are still animated when you move your mouse over them (a subtle fade-in / fade-out animation). Every single bit of animation throughout Windows is gone, but those 3 buttons remain animated.

Is there any registry hack or something else to disable their animation, or it's hard-coded? The only way to get rid of it is to use the Windows Basic theme and disable Aero, but the interface seems to have better performance with the Aero enabled. Thanks in advance.

Hello ThrashZone.

Try enabling the "Show shadows under windows" option - it makes the fade in / fade out effect more visible (watch the red glow of the Close button). Like I said, all animations are gone, but animations of those three buttons remain.

You might not see them very well - the fade in / fade out is fast, but it's still there. Those three buttons act like the "Animate controls and elements inside windows" option is enabled. Try enabling that option and move your mouse across the dialog box buttons (OK / Cancel / Apply).

Now disable that option and move your mouse across them again. Notice how there's no fade in / fade out animation anymore? The only problem is that it doesn't apply to Minimize / Maximize / Close buttons - they are always animated.

I don't see how graphics card or its memory relate to this bug.
