Research direction
Start by diffing the git tags for 2.8.0 and 2.9.0 to find what changed in the keystroke/input-source tracking path that runs on every keypress. Profile the 2.9.0 build with Instruments (Time Profiler) while triggering the Alfred/Spotlight search field to locate the added work on the main thread. Done looks like identifying the specific commit or code path responsible for the regression, with a fix that restores 2.8.0-level responsiveness and is verifiable by reproducing the lag in Alfred or Spotlight.

Description
开启了InputSourcePro之后，打开Alfred或者Spotlight的搜索框，输入时可以感到明显的卡顿。之前都是非常流畅的，应该是更新到最新版本，才存在这种卡顿。

在视频左下角可以看到击键情况（请注意，它很容易被进度条挡住）。
当我回退到2.8.0版本，这个问题就消失了。
