I used to get a crackle/pop (and a screen flash) when I had "Display Refresh" enabled in my settings.
(Settings/System/Advanced Display Settings/Auto-Adjust Display Refresh Rate). Perhaps try toggling that to a different setting and see if that helps.
If you need the setting enabled, then try using a different Screensaver. (since you mentioned it occurs after the standby/low power mode).
