If the Limit Window Exposures setting is disabled, enabling backing store reduces network traffic and improves window refresh speed at the expense of window drawing speed and memory. You can define the circumstances under which backing store is used.
To configure backing store settings:
Setting |
Value |
---|---|
MaximumLimits the amount of backing store provided when you let the X application specify the amount. You can set this value to None, When Mapped, or Always. The resulting backing store conforms to the X application request or the maximum setting, whichever is lesser. |
NoneNever save the contents of the X application window. |
DefaultDetermines the amount of backing store provided to an X application that does not specifically request backing store. You can set the default backing store value to None or When Mapped. This setting is applicable only when you set the maximum backing store to a value other than none. |
NoneNever save the contents of the X application window. |
MinimumThis is applicable only when you have specified a maximum backing store, and you have set the default backing store value to When Mapped. The resulting backing store conforms to the X application request or this value, whichever is greater. You can set the Minimum Backing Store to None or When Mapped. |
NoneNever save the contents of the X application window. |
