Android 17 QPR1在9月15日发布后，Pixel内核驱动树出现严重性能回归1。该问题表现为内存压力下的卡顿、滞后和冻结现象，甚至导致进程被杀死1。GrapheneOS团队已在今日发布的版本中修复了这一问题1，而谷歌的修复时间表仍不明确1。
此前，Pixel 11系列于9月初收到bug修复版本，补丁级别为2026-09-011。根据历史规律，谷歌修复严重问题通常需要2至3个月，主要Android版本的修复周期则需要4至6周1。GrapheneOS计划在2026年11月前发布内存优化改进1。
GrapheneOS has resolved a significant kernel performance regression that emerged following the release of Android 17 QPR1 on September 15, 2026 1. The issue, which affected Pixel devices, manifested as stuttering, lag, and freezing under memory pressure, with processes being terminated in severe cases 1. The GrapheneOS team deployed the fix in today's release 1.
The regression had impacted the Pixel kernel driver tree, and Google's timeline for addressing the problem remains unclear 1. Industry patterns suggest that Google typically requires two to three months to fix severe issues, though primary version fixes generally take four to six weeks to complete 1. The Pixel 11 series received a bug fix update in early September 2026 with a patch level dated September 1, 2026 1. GrapheneOS has indicated plans to roll out memory optimization improvements before November 2026 1.
