[imx8mp][android] WebGL Aquarium rendering issue

jason9816 — Wed, 19 Mar 2025 07:19:51 GMT

As the title says, we encountered flickering and graphical issues when running the WebGL Aquarium demo on our NXP i.MX8MP SoC custom board with Android 12-15. I also tested it on an NXP i.MX8MP EVK board with the 15.0.0_1.0.0_DEMO_8MP Android prebuilt images, and the issue remains.

Previously, we tested the same setup on our NXP i.MX8MP SoC custom board running Android 12-14 about a year ago, and it was working fine at that time. However, the issue seems to have appeared this year.

We have attached a recording from our NXP i.MX8MP SoC custom board running Android 15 to showing the issue.

Hello,

Weston is one process using GPU. It's able to see chromium-bin in the process list of gputop also. When browsering "webglsamples.org/aquarium/aquarium.html", we can see GPU usage going high.

If chromium runs with "chromium --no-sandbox --disable-gpu", we can observe chromium-bin is not in GPU process list and usage is null. Also the web shows empty with "webglsamples.org/aquarium/aquarium.html". That proves GPU is enabled without "--disable-gpu".

regards

Hello,

Yes, I have tested it on our Yocto 5.0 OS, and it worked fine. The flickering issue seems to occur only on Android. Is this a known issue on Android?

Correct! is a known issue on Android devices.
