GrapheneOS has fixed the Android 17 QPR1 kernel performance regression

GrapheneOS has fixed a severe performance regression in Android 17 QPR1's kernel that caused stuttering, lag, and freezes under memory pressure, while Google continues to take 2-3 months to ship fixes for major issues. The GrapheneOS team released a patch addressing the problem and criticized Google's slow release engineering and testing processes, noting they are increasingly having to handle quality control and updates themselves for the entire operating system.
