I'm using selenium-docker project to run chrome inside a docker container, without XVFB (START_XVFB=false).
I want to use webgl support. With chrome v95 and lower (https://github.com/SeleniumHQ/docker-selenium/releases/tag/4.1.0-prerelease-20211105), webgl is enabled (checking with https://get.webgl.org/).
However, when using chrome v96 or later it doesn't work (https://github.com/SeleniumHQ/docker-selenium/releases/tag/4.1.2-20220131). I can see that the gpu-process has --use-gl=disabled argument, this does not happen with chrome v95.

I have tried passing arguments to chrome but they don't work. I believe selenium image has nothing to do with this behaviour, it's something that changed in chrome v96.
Enabling XVFB is not an option for me, performance is not the same.
How can I avoid this --use-gl=disabled argument being passed to the chrome gpu process?
This is the ps ouptut with chrome 94, here swiftshader is selected:

It works out of the box with chrome 104, no need for any --use-gl flags
