Mysterious Stuttering

[11156]

First of all, I would like to thank you for always allowing me to use Three.js.

Recently, we have noticed that the behavior is stuttering only in some environments.

Those environments are

• Pixel 7 Pro Chrome (Android 13)
  (confirmed on two “Pixel 7 Pro” devices)

I tested the following environments and this did not happen

• Pixel 6 Pro Chrome (Android13)
• Pixel 7 Pro Edge
• iPhone 11 Pro Safari
• Mac Chrome
• Windows Chrome

Checking performance with the Chrome Devtool, it appears that there are frames where no processing is being performed, rather than “one process does not fit within a frame”.

The version of three.js is 0.127.0.

Attached is a performance image of Pixel 7 Pro when this phenomenon occurred. The area circled in red is where the “frames not being processed” are clearly visible.

Is anyone else experiencing the same problem?

Updated question

• Updated to three.js 0.148.0 and observed the same problem.
• Using FireFox on Pixel 7 Pro, same problem.

Do you see the same performance issues with Firefox on your Pixel 7 Pro?

Thanks for your reply.

I tried using FireFox with Pixcel 7 Pro.
As you said, the same phenomenon occurred.

How did you know this?

It was just a wild guess since what you have described sounds like a typical device issue. You might want to report the issue to the Chromium bug tracker though (although I suspect it is related to the SoC driver or something similar).
