Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
Reproduction steps:
1. Open the “ZIPPEDPROJECT” attached project
2. In the Menu bar click on File > Build Settings
3. Change Platform to WebGL
4. Click on “Unity Support” in the Menu bar
5. Press “Build & Run Player”
6. Copy the build URL from your default browser to Firefox, Chrome and Safari
7. Observe FPS count in the browsers
Expected result: Build on Chrome runs smoothly with 60fps (has a similar performance compared to Firefox and Safari)
Actual result: Build on Chrome is laggy with ~20 fps (lower performance compared to Firefox and Safari)
