Description

Enables window occlusion in Microsoft Edge. If you enable this setting, to reduce CPU and power consumption, Microsoft Edge detects when a window is covered by other windows, and suspends work painting pixels. If you disable this setting, Microsoft Edge doesn't detect when a window is covered by other windows. If you don't configure this policy, window hiding detection is enabled.
