Do you get a white dot on the top-left corner of your Windows 7 screen when an Aero theme is selected and “Enable transparency” is unchecked?
It appears that this is a known issue in Windows 7, and Microsoft is very much aware of it!
One white dot of size, 1 pixel, could appear on the top-left corner of the screen in the following scenarios:
In Windows 7 Home Basic Edition, the issue may occur after a user selects the “Windows 7 Basic” color theme and changes the wallpaper.
In Windows 7 Ultimate and other editions listed in the “Applies to” section, this issue may occur after a user selects an Aero theme and then un-checks “Enable transparency”.
Applies to Windows 7 Home Basic, Windows 7 Professional, Windows 7 Home Premium & Windows 7 Ultimate.
Well I tried it and didn’t get the dot! Do you?

Thanks for the screen-shot Ravi!
