Well, adding the same parameters to electron as the one used in /usr/lib/chromium/chromium-wrapper, I can see an improvement.

GPU usage is now registering in 'tinker-power-management', but GPU usage is still around 50% for a FHD video.

The error in the post above is still present.

Here are the aforementioned flags : 

--use-gl=egl --no-sandbox --gpu-sandbox-start-early --enable-accelerated-video-decode --ignore-gpu-blacklist --ignore-gpu-blocklist

AFAII, it's using some userland drivers/decoders for the mali chip ?

So: someone said this on the now dead tinkerboarding.co.uk :

This error message is caused by the userspace application try to use the OpenGL API.
However, Tinker Board can only support OpenGL ES but not OpenGL API.
So you need to use the OpenGL-ES API instead of OpenGL.

Also, the missing file should be in libgl1-mesa-dri

hello @Remontoir,

yes, tinkerboard/ tinkerboard s only supports opengl es-- which test are you running? perhaps we can run it our side and see what comes out.

It's to run an electron app. I managed to make it run with some flags passed to chromium ( something like '--use-gl=egl' ).
