Pre-built Chromium Results in Jittery WebGL

[Ben93kie]

Hi, thanks for this helpful repo!
When downloading and running the pre-built Chromium, it does not run natively on my

Jetson AGX Orin 64GB with Jetpack 5.1.

Instead, I had to run it via

/usr/bin/chromium-browser-unstable --no-sandbox --use-gl=egl --enable-gpu-rasterization --ignore-gpu-blacklist

While it did show all the hardware accelerations in chrome://gpu, when visiting https://threejs.org/examples/, the scene jitters and wiggles all around. I suspect there is a driver issue?

Do you have any advise on how I would change the build process to accommodate my setup?

Thanks!

Sorry, an update:
If I run like like this:

/usr/bin/chromium-browser-unstable --no-sandbox

I don'get the jitter, but raserization is CPU-only:

Graphics Feature Status
Canvas: Hardware accelerated
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Disabled
OpenGL: Enabled
Rasterization: Software only. Hardware acceleration disabled

Is there any way to also have it GPU-accelerated? I'd like to have a threejs scene with maximum hardware accleration.
Thx!
