RC8 (App Store Version) Tearing has returned

  • I bought RC8 from the Apple App Store a while ago. The initial version had an issue with Video tearing, which was fixed in a new version. Recently there's been an App store upgrade and since I installed that the tearing has returned.

    Is there anything I can do to get rid of it? It gives me a headache trying too use RC8 like this.

    I'm using a Late 2015 27" iMac with 5k Retina display, High Sierra.
