Possible Values

vBuffering

Boolean that specifies or receives one of the following values. auto Default. String that allows Microsoft® Internet Explorer to decide when offscreen buffering is used. true Boolean that enables offscreen buffering. false Boolean that disables offscreen buffering.

The property is read/write. The property has a default value of auto.

Remarks

The value of the offscreenBuffering property determines how the current page is drawn. When the property is set to true, objects are added to an offscreen buffer. Once all objects are drawn, the contents of the offscreen buffer are made visible to the user. When the property is set to false, objects are rendered directly to the screen.

By default, Internet Explorer decides when to buffer objects offscreen. In addition, Internet Explorer automatically enables offscreen buffering when Microsoft DirectX®-based components are used on the page.
