  • Android Authority 's TL;DR (conveniently) doesn’t mention the actual downside to this update. But it’s fine imo, since this was actually a pretty insightful read.

    My TL;DR:

    • Google’s ARR/VRR implementation is hopefully more compatible with the GKI system vs. current per-vendor, per-device implementations
    • To add this support, vendors must implement v3 of the Hardware Composer and Hardware Abstraction Layer APIs.
    • That means also undoing existing kernel changes for their devices and retooling it to support HWC & HAL v3. Lots of engineering time.
    • This solution still isnt perfect. There’s a notable limitation in something called the “panel’s Tearing Effect”, but im not an expert at displays so CTRL+F it for the paragraph in question.
