Everything works perfectly fine, but when I try to open the Vehicle Manifest or the Kharak Data Presentation in the Expedition Guide it says that "You need a browser which supports WebGL to run this content. Try installing Firefox"

Now, I don't think that the expedition guide is actually trying to access any internet browser. I believe it is using some sort of mini browser of its own.
Notwithstanding, I tried to change my actual browser setting; switching between Chrome and Firefox being the default, activating and confirming WebGL being active in both etc. None of that changes anything of course.

The problem obviously lies with the Expedition Guide itself.

I am using Linux Kubuntu, and of course run all Windows programs through Wine.

If you have any advice on how to fix this I would greatly appreciate it.
