NanoPi M4 Hardware Acceleration Video WebGL

[pocketvj]

Hi

I am trying to run a WebGL video on my NanoPi M4
here is the link: https://mapper.jku.one/

It does not play fluent at all!
On the wiki stands that NanoPi supports OpenGL.

When checking the settings://gpu in Chromium, I can read: "Hardware acceleration unavailable"
How can I activate the OpenGL Mali driver and get full HW support for the webbrowser?

Any hints are very welcome.
Thanks.

Use firefox. Only works on 64-bit. But it works perfect.
A good second best is Vivaldi Browser, better for surfing, but not perfect for video.
In firefox no dropped frames.
