Screensavers start to hang after couple of minutes
After upgrade to Mojave, all screensavers start stuttering within minutes. This includes Apple's own savers, like Flurry and Aerials. Video's from Aerials still play fine in VLC and Quicktime; so it seems to be a problem with the screensaver-system itself.
