A mirror driver that is attached to the whole desktop cannot correctly draw the desktop background wallpaper in Windows XP (899857)


The information in this article applies to:

  • Microsoft Windows XP Home Edition
  • Microsoft Windows XP Professional

SYMPTOMS

In Microsoft Windows XP, a mirror driver that is attached to the whole desktop cannot correctly draw the desktop background wallpaper if the desktop covers more than one monitor.

RESOLUTION

To resolve this issue, turn off the desktop background before you use an application that mirrors multiple monitors.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

On the physical monitors, the desktop background wallpaper is drawn so that it is centered on each monitor. However, on the mirrored virtual desktop, the desktop background wallpaper is centered over the whole virtual desktop. Additionally, the wallpaper is the size of the first physical monitor. When the background painting occurs, the source of the drawing is the physical monitor instead of the mirrored virtual desktop. Therefore, background image corruption occurs.

The following applications typically mirror the desktop:
  • Screen capture
  • Remote administration
  • Help desk
