Window Info provides incorrect color on Windows 8?

[GregoryBloom]

I tried using the AutoIt Window Info tools (both x86 and x64) to identify the color of specific pixels being displayed in the browser (Chrome) window.  The reported color hex values bear no resemblance to the actual colors under the Finder Tool target cursor.  For instance, as I drag the Finder Tool across the blank area in the text box where I'm writing this message, I see values 0xFFFFFF (expected), 0x204066, 0x1C3B5F, 0x142B46, etc.  The Title and Class are reported correctly, and the other information seems right.  Is there something about Windows 8 or Chrome that prevents the Window Info Tool from accessing the pixel color?

UPDATE: I just tried it on an empty notepad.exe window.  Same results - despite sampling a blank white text area, the color reported varies wildly.  What's up with that?

Try this. It is a stand alone pixel get color and coords. Notice how the coordinates will change if you select a window. The coords you get when you first run the script are accurate so long as you don't click anything.
