Frame Drop Issue on Web Platform in Cocos Creator 3.8.3 or Later Versions

While developing a web client using Cocos Creator version 3.8.4, I discovered intermittent frame drops during execution.
Although the reproduction video shows that the issue occurs at similar intervals, the actual occurrences are irregular. Additionally, the frame drops persist throughout the execution rather than happening only once.

Is there a solution to this issue?

I have noticed it as well with my project after upgrading from 3.7.1 to 3.8.5.

Tks for your feedback, we will check it out.

Would using a frame pacing library help resolve this?

The issue occurs on my computer, which has been feedback to engineer to fix it. Tks for your feedback, that will help us improving engine quality, stability, performance。

It sounds like a tough issue with frame drops. Have you tried optimizing the rendering settings or checking for memory leaks? Also, testing with a different version or clearing cache might help isolate the problem. Hopefully, this leads to a smoother experience!
