Client Area Animation
The client area animation flag indicates whether the user wants to disable animations in UI elements. Display features such as flashing, blinking, flickering, and moving content can cause seizures in users with photo-sensitive epilepsy. This flag enables you to enable or disable all such animations.
Applications use the SPI_GETCLIENTAREAANIMATION and SPI_SETCLIENTAREAANIMATION flags with the SystemParametersInfo function to turn client area animations on or off.
