Description Ryosuke Niwa 2023-04-04 01:08:02 PDT 
With STP167, playing YouTube video while building WebKit in parallel results in the video stutters intermittently.

Reproduction steps:
1. Play YouTube video
2. Start full WebKit build

Expected result:
Video plays smoothly

Actual result:
Video stutters

Music app can play music fine so this isn't a system recession. Safari 16.2 can play the video while building WebKit just fine on the same system as well.
