… workers. MemoryPressureHandler accounts for GPU memory in every WPEWebProcess and has no way to distinguish whether it is the main web process or a service worker. In conjunction with s_videoMemoryInFootprint, footprint calculations subtract high GPU memory usage of the main web process from the low RSS memory value of a service worker, which results in an overflow and triggers critical memory pressure for the service worker.
