When using The Marvellous Suspender, you can use chrome’s built-in ‘tab discarding’ which saves up to 500% memory, but it will flash a white screen every time you change to a suspended tab. This is because there is a slight rendering delay when selecting a suspended tab. Discarded tabs or unrendered tabs might be white in chrome and brave. If the discarded tab was black instead, it would be better for eyes and oled screens when it’s accidentally shown.
