A white or black rectangle may appear on the desktop of your primary monitor.
Cause
This behavior may occur when a program uses Microsoft DirectX Application Programming Interfaces (APIs) to switch the screen resolution to a smaller size. When this occurs, the desktop from the primary monitor may be displaced to the secondary monitor. Note that this symptom disappears when you quit or minimize the program that caused the resolution change.
