Beta/Release Uplift Approval Request

• User impact if declined: Bug 1618370
• Is this code covered by automated tests?: No
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): This disables DirectComposition completely in 74. Since it's been on for most of the 74 cycle there's some risk that the non-DirectComposition could have regressed but that's unlikely. We also had DirectComposition turned off during a portion of the 75 cycle without issue.
• String changes made/needed:
